What can someone do with your IP address? Risks, solutions, and expert tips

Imagine someone peeking into your private world through a digital keyhole. They might not see everything, but they can learn more than you’d like: your location, the devices you use, and even your online habits. That’s the reality of your public IP address—it’s a unique identifier that leaves a trail every time you go online.

Your IP address is essential for connecting to the internet, but it also comes with risks. From targeted ads to cyberattacks, your IP can reveal more about you than you’d expect. Luckily, tools like VPNs can help protect your privacy and take back control.

In this guide, we’ll explore what your IP address reveals about you, what someone can do with your IP address, and—most importantly—how to protect it.

Understanding IP addresses

Your IP address is the key to connecting to the internet. It helps your device communicate with websites and services, but it also holds more information about you than you might realize. Let’s break down what an IP address is and why it matters for your privacy.

What is an IP address?

An IP address (Internet Protocol address) is a unique string of numbers assigned to your device by your internet service provider (ISP) when you go online. Think of it as your device’s online ID, allowing it to communicate with other devices and websites.

There are two types of IP addresses: IPv4 (e.g., 192.0.2.1) and IPv6 (a newer format designed for the growing number of devices online). An IP address is necessary for connecting to the internet, but it can also reveal information about you—like your general location.

Can an IP address show your location? 

Yes, an IP address does show your location. It doesn’t show your exact address but can pinpoint your city, region, and ZIP code. This is because ISPs assign IP addresses in specific geographic ranges.

Websites and services often use this information to personalize ads and content based on where you are. However, anyone with the right tools can trace your IP address and use it to find your general location. To see what your IP address reveals, use our IP checker tool.

How is your IP address assigned?

Every time you connect to the internet, your ISP assigns your device an IP address. This process happens automatically using a system called DHCP (Dynamic Host Configuration Protocol), which ensures each device has a unique identifier while online.

Think of it like checking into a hotel. The hotel assigns you a room number for your stay, allowing staff to know where to send room service or deliver messages. Similarly, your ISP assigns an IP address to your device so it can send and receive data online.

There are two types of IP addresses: static and dynamic.

• Dynamic IP addresses: These are the most common type. They change periodically—such as when you reconnect to your network or restart your router. Dynamic IPs are cost-effective and provide basic functionality for everyday internet users.
• Static IP addresses: These stay the same and don’t change over time. They’re often used for specific purposes like hosting websites, running a server or accessing a home network remotely. Static IPs are less common for regular internet users but are useful in certain setups.

Public vs. private IP addresses: what’s the difference?

A public IP address identifies your location on the internet so data knows where to go. Private IP addresses identify individual devices within your local network. Only the public IP address is visible when you go online.

Here’s how they work together:

• Public IP address: This is the address assigned to your device by your ISP, visible to websites and online services. It’s how your device communicates with the internet. When you visit a website, the website traces your public IP address so it knows where to send the information you’ve requested.
• Private IP address: These are used within your home or local network to identify devices like your laptop, smartphone, or smart TV. For instance, when you stream a movie from your smart TV, your network uses IP tracing to find the correct private IP address for your device. This ensures data reaches the correct device within your network.

What does my IP address reveal about me?

Your IP address is like a digital fingerprint. So, knowing what your IP address reveals is an important part of understanding your digital privacy. Let’s break it down:

Your geographic location

Your IP address gives away your general location, such as your city, region, or ZIP code. This is because ISPs assign IP addresses in blocks tied to specific geographic areas.

For example, if you’re browsing from New York, your IP address might show that you’re somewhere in the New York metro area, but it won’t reveal your exact home address. So, while an IP address can be traced to a location, it won’t give precise details.

Your Internet Service Provider (ISP)

Your IP address identifies your ISP, letting others know which company provides your connection. For instance, it might indicate that your connection comes from Comcast, AT&T, or another ISP.

Websites often trace IP addresses to provide location-based services, such as showing localized content or offering regional pricing. For example, an online store might use your IP address to display prices in your local currency, while a streaming platform could limit content based on your location.

Unfortunately, this information can also be exploited. Advertisers may start tracing your IP address to target you with location-based ads or combine it with other data to create a more detailed profile of your online behavior. 

Worse, hackers could use your exposed IP address as a starting point to gather more information about your device or network, potentially exploiting vulnerabilities for malicious purposes. 

Your online activity (potential tracking)

Websites and trackers can use your IP address to monitor your online activity, such as the sites you visit or services you access. Over time, they might use this data to build a profile of your browsing habits and preferences. For example, if your IP address frequently accesses travel websites, advertisers might start showing you targeted ads for flights or hotels.

While your IP address alone doesn’t reveal your full browsing history, it acts as a digital marker that connects your activity across different websites and apps. This is why understanding what people can do with your IP is crucial. This seemingly small piece of data can significantly compromise your privacy, especially if combined with other information, like your device information or login details.

Limitations: what your IP address doesn’t reveal

Your IP address can’t reveal everything about you. Here are some key limitations:

• Your exact physical address: Your IP address can reveal your approximate location, such as your city or region, but it won’t provide your street address or apartment number. This level of precision would require additional data, like GPS coordinates, which your IP address doesn’t provide.
• Personal details like your name, age, or phone number: Your IP address is a technical identifier tied to your internet connection, not to you as an individual. It doesn’t include personal information such as your name, birth date, or contact details. Your IP address can’t directly link to your identity unless combined with other data (e.g., account details from a data breach).
• A full breakdown of your browsing history: Your IP address doesn’t store your browsing history. It serves as a way for websites and services to send data back to your device. Advertisers and websites can track your activity using cookies or other tools, but they can’t directly pull your browsing history from your IP address alone. For example, an e-commerce site can track what you’ve viewed on its platform, but your IP doesn’t reveal all the other websites you’ve visited.

What your IP address can and can’t reveal

Here’s a quick overview of all the information an IP address can reveal about you:

How can someone get your IP address?

Your IP address isn’t as private as you might think. Whether through everyday activities like browsing or more targeted tactics, there are several ways to trace your IP address. Let’s go through how someone can get your IP address.

Clicking on suspicious links

When you click on a link, your IP address is automatically shared with the website you’re visiting. This is necessary for the website to deliver content to your device. That said, malicious links or untrustworthy sites can exploit this by logging your IP address for tracking purposes.

For example, advertisers may log your IP to refine your profile for targeted ads, while phishing links can use tracking tools to gather details like your ISP and general location. 

Through public Wi-Fi networks

Public Wi-Fi networks expose your IP address to anyone monitoring the network. Hackers can use tools to intercept traffic and uncover your IP, leaving you vulnerable to data breaches or attacks.

For example, a cybercriminal could exploit weak router settings to not only find your IP address but also infiltrate your device. This is one way that tracing IP addresses on public networks can lead to significant privacy risks.

From online forums or gaming platforms

Every time you post on an online forum, the forum administrator can see your IP address in their server logs. This happens even if you don’t log in or provide personal details.

Many online gaming platforms also record player IPs to manage connections and gameplay. These IP addresses may be visible to other players, which could allow someone to get your IP address and target you with threats like DDoS attacks.

Even if your personal details aren’t included in the forum or game, attackers can combine tracing IP addresses with other public data to uncover more about you, increasing your IP address risks.

Via email headers

Your IP address may be included in the header of emails you send. Although many modern email providers mask this data, some still expose it. A recipient could view the header and use your IP address to trace your location or ISP.

Hackers may also target you via email to get your IP address. They might send phishing emails with links designed to log your IP when you click or use spoofed email headers to trick you into responding. 

Once they get your IP address, they can use it to track your activity, launch attacks like DDoS, or even craft targeted phishing campaigns based on your location and network.

Torrenting and peer-to-peer sharing

When you torrent or participate in P2P sharing, your IP address is visible to everyone in the network. Torrent trackers record all participating IPs, allowing others to trace your IP address to your approximate location or ISP.

This exposure can pose significant IP address risks, as it may leave your information visible to others on the network. For example, third parties monitoring activity could log your IP address, potentially leading to unwanted surveillance or other privacy concerns.

Using IP grabbers and trackers

IP grabbers such as Grabify generate short links that track anyone who clicks them. These tools collect details like your IP address, ISP, and location. Once logged, this data can be used to trace your IP address and target you with phishing attacks or even identity theft schemes.

Even seemingly harmless links on social media or in emails can hide these tools, so it’s important to verify links before clicking.

What someone can do with your IP address? 

Your IP address might seem like just a random string of numbers, but in the wrong hands, it can reveal more about you than you might expect. From tracking your location to tracking your activity, exposing your IP address can lead to serious privacy and security risks.

Let’s examine what others can do with your IP address and why protecting it is so important.

Trace your geographic location

When someone knows your IP address, they can use it to find your approximate location. This can leave you vulnerable to various IP address risks and restrictions, including:

• Targeted advertising: Advertisers can tailor their ads to your region, promoting local services or products based on where your IP is traced.
• Geographic restrictions: Websites or streaming platforms might restrict access to certain content if your IP address is traced to a region where it’s unavailable.
• Narrowing down your whereabouts: While an IP doesn’t reveal your exact location, a malicious actor could combine it with other publicly available data to pinpoint your address or identity.

Block you from accessing websites

Your IP address can be used to restrict your access to certain websites or online services. Websites, organizations, or governments often do this to control who can view their content or use their platforms.

Here are some common scenarios:

• IP bans: Websites can block specific IP addresses if they suspect unusual activity, such as spamming or violating their terms of service. For example, a gaming platform might ban your IP if it detects rule-breaking behavior, even if it wasn’t intentional.
• Geo-restrictions: Streaming services and websites often limit content based on your location. If your IP address is traced to a region where the content is unavailable, you may be denied access.
• Firewalls: Schools, workplaces, and even governments can block your IP address from accessing certain websites, especially streaming or social media platforms.

Launch DDoS attacks

If someone has your IP address, they can use it to target you with a DDoS attack. This type of attack involves overwhelming your network or device with a flood of data requests, making it impossible for you to access the internet or use online services.

Here’s how it works:

• IP targeting: An attacker identifies your IP address and directs a massive amount of traffic to your network.
• Overloaded connection: This surge of traffic overwhelms your internet connection, slowing it down or completely disabling it.
• IP spoofing: In some cases, attackers can make the requests appear as if they’re coming from your IP, potentially implicating you in malicious activity.

DDoS attacks are often used in online gaming to disrupt opponents or as part of larger cybercrime threats. While they don’t directly compromise your personal information, they can cause significant disruptions and even damage network equipment.

Track your online activity

Your IP address plays a key role in how advertisers and websites monitor your behavior online. By linking your IP to the websites you visit and the services you use, they can track your activity and build a detailed profile of your habits and preferences.

This tracking might seem harmless, but it’s a significant IP address risk for your privacy. Here’s how it works:

• Combining IP and cookies: Websites often pair your IP address with browser cookies to identify you uniquely, even across different sessions. For example, if you frequently shop for sports gear, advertisers may use your IP and cookies to show you related ads wherever you browse.
• Cross-device tracking: Since all devices on the same Wi-Fi network share the same public IP address, trackers can combine this data to link multiple devices to a single household.
• Behavioral profiling: Over time, this data is used to create a comprehensive picture of your interests, habits, and online behavior. This profile might then be sold to third parties or used to target you with highly personalized ads.

Run personalized phishing campaigns

If you’ve commented on blogs, forums, or websites, your IP address might be visible to administrators or stored in server logs. If someone has your IP address, they can use this with other publicly available details, such as your name, location, or interests, to create convincing phishing emails.

For example, knowing your location through your IP might allow an attacker to send a phishing email inviting you to a local event, making it more likely for you to fall for the scam. This level of personalization increases the effectiveness of phishing campaigns and poses a significant privacy risk.

Impersonate you for fraudulent activities

With access to your IP address, malicious actors could potentially impersonate you online. By using your IP, they might carry out activities that appear to originate from your device or network. This could include:

• Spamming or illegal downloads: Hackers could use your IP address to send spam emails or download illegal content, falsely implicating you.
• Identity theft: Your IP alone doesn’t reveal personal information, but it can be combined with other data to impersonate you on certain platforms or commit fraud.
• Online scams: Fraudsters might use your IP to bypass certain security measures on websites or create accounts under your identity.

Get you in trouble for copyright infringement

Your IP address can be used to link your online activity to your network, which is why it’s often monitored in cases of copyright infringement. For example, if copyrighted material is downloaded via your IP, it could serve as evidence in a legal case.

This typically begins with a warning letter from your ISP, notifying you that your IP address has been associated with unauthorized downloads. In more severe cases, repeated offenses could escalate to lawsuits or penalties, even if the downloads were accidental or conducted by someone else on your network.

Hack your device 

Hacking a device using just its IP address is difficult but not impossible. Cybercriminals typically rely on more straightforward methods like phishing or smishing, but an exposed IP can still pose risks.

One method hackers might use involves targeting open ports on your network, which act as entry points for data. If these ports aren’t properly secured, attackers could brute-force their way in, potentially gaining access to your device. This could allow them to install malware, steal information, or disrupt your system.

Another concern is the misuse of your IP address, which makes it appear as though illegal activity originated from your device. For example, cybercriminals could use your IP to download illegal content, framing you for actions you didn’t commit. 

Sell your IP address on the dark web

In the wrong hands, your IP address can become a commodity on the dark web. Cybercriminals who gain access to your IP might bundle it with other data, such as browsing activity or device details, and sell it to buyers on the dark web so they can exploit it.

Once sold, your IP address could be used for various purposes, such as launching cyberattacks, creating fake accounts, or masking illegal activity. For instance, someone could use your IP to disguise their location while engaging in fraudulent schemes.

Execute targeted malware attacks 

Hackers can use your IP address to launch targeted malware attacks, often by probing for vulnerabilities in your network. They might gain access to your router, especially if the default password hasn’t been changed. Once inside, they can install malware that compromises not just your device but your entire network.

Another common method is the man-in-the-middle attack, where hackers intercept data being transmitted over unsecured Wi-Fi networks. By exploiting your IP address, they could inject malware into your connection or eavesdrop on sensitive information.

What can a hacker do with an IP address?

Your IP address is more than just a number—it’s a gateway to your network. Your IP address won’t hand over sensitive data, but skilled hackers can exploit it to uncover vulnerabilities, monitor your activity, or even launch larger cyberattacks.

Let’s explore the specific IP address risks and what hackers might do with your IP address.

Exploit network vulnerabilities

A skilled hacker can use your IP address to search for weaknesses in your network. By scanning for open ports or outdated software, they may find entry points to exploit. Open ports act as doorways for data to travel in and out of your network, and if they’re not properly secured, they can be targeted for unauthorized access.

Once inside, hackers might gain control over connected devices, install malware, or steal sensitive information. For example, an exposed router with default settings can allow hackers to manipulate your internet traffic or disrupt your connection entirely. These network vulnerabilities can have drastic consequences for your privacy and security, especially in unsecured home or public Wi-Fi networks.

Spy on your online behavior

Your IP address can act as a digital breadcrumb, allowing hackers to monitor your online activities. If a hacker pairs your IP with other tracking tools, such as cookies or browser fingerprints, they can monitor the websites you visit, the services you use, and even how long you stay online.

This type of monitoring might not give hackers direct access to your personal data, but it helps them build a profile of your habits and interests. Over time, this information could be sold to third parties or used to craft targeted phishing scams that exploit your specific behavior or preferences.

Access sensitive information

An exposed IP address can make it easier for hackers to target your personal data. By combining your IP with phishing attacks, malware, or other tools, they may gain access to sensitive information such as:

• Login credentials: Hackers might intercept usernames and passwords for your accounts, potentially leading to identity theft.
• Financial details: If you access banking websites or make online purchases on unsecured networks, attackers could steal payment information.
• Personal files: Cybercriminals might use your IP to infiltrate your device and extract private documents, photos, or communications.

An IP address isn’t enough to access this information directly, but it can help hackers identify and target devices where sensitive data is stored—especially if combined with weak security practices or malware.

Launch large-scale cyberattacks

Hackers can use your IP address to carry out larger, coordinated attacks on networks, websites, or services. One common method is to recruit devices into a botnet—a network of compromised devices used to carry out cyberattacks like DDoS.

By exploiting your IP address, attackers might:

• Turn your device into a botnet participant: Your device could be secretly used to send massive amounts of traffic to a target, overwhelming their servers.
• Hide their activity: A hacker could use your IP to mask their true location while carrying out attacks, making it harder to trace the origin.

Even though you might not notice the effects immediately, being part of such an attack can slow down your network, reduce performance, or make you falsely implicated in malicious activities.

How to recognize hacker activity

If your IP address has been compromised, there are often signs that your device or network is being targeted. If you notice any of these signs, it’s crucial to investigate further and secure your IP address to prevent additional exploitation.

Here are some common indicators:

• Unusual internet slowdowns: A compromised network might experience slower speeds, especially if someone is tracing your IP address for botnets or DDoS attacks.
• Unauthorized access or logins: Notifications about logins from unfamiliar locations or devices could indicate your IP is being misused.
• Increased data usage: A sudden spike in your internet data usage may suggest that your network is being exploited for malicious activities.
• Pop-ups or ads: If you see an increase in intrusive ads or pop-ups, it might mean your IP has been targeted, possibly through malware.
• Unfamiliar devices on your network: Devices you don’t recognize connected to your Wi-Fi might indicate unauthorized access.

Is tracing an IP address legal?

Yes, tracing an IP address is legal in many situations, as long as it’s done for legitimate purposes and within the law. However, when used maliciously or without consent, IP tracking can raise legal and ethical concerns. Let’s explore the considerations and consequences of tracing an IP address.

Ethical and legal considerations of IP tracking

Tracing an IP address is generally legal when done transparently and for lawful purposes. For example, websites and services often track user IPs to manage traffic, enforce regional content restrictions, or protect against cyberattacks. These activities are typically outlined in privacy policies and comply with data protection laws.

IP tracking crosses ethical and legal boundaries when it’s used without consent for malicious purposes. For instance:

• Hacking or stalking: Using IP tracking to harass or harm someone is a clear violation of laws in most countries.
• Data harvesting: Tracking IPs to build unauthorized profiles of individuals can breach privacy laws like GDPR or CCPA.
• Unauthorized surveillance: Collecting IP data without disclosing its use to users may result in penalties or lawsuits.

When is IP address tracing allowed?

Tracing an IP address is allowed in many cases when it serves a lawful or legitimate purpose. Common scenarios include:

• Network troubleshooting: ISPs and IT administrators use IP tracking to diagnose network issues, improve performance, or prevent unauthorized access.
• Fraud prevention: Businesses may trace IP addresses to detect and block suspicious activity, such as login attempts from unusual locations or patterns that indicate fraud.
• Content restrictions: Streaming platforms or websites often use IP tracing to enforce geographic restrictions or comply with licensing agreements.
• Law enforcement investigations: Authorities can trace IP addresses as part of investigations into cybercrimes, fraud, or other illegal activities, often with legal authorization.

Consequences of misusing IP information

Misusing IP address information can lead to serious legal and ethical repercussions. Here are some common consequences:

• Violation of privacy laws: Laws like the GDPR and CCPA impose strict penalties for unauthorized data collection, including IP tracking without consent. Companies or individuals who breach these regulations may face significant fines.
• Civil lawsuits: Using IP information to harass or stalk someone could lead to civil suits for invasion of privacy, defamation, or emotional distress.
• Criminal charges: In cases involving hacking, fraud, or malicious activities linked to IP misuse, offenders may face criminal prosecution.
• Loss of reputation: For businesses, unauthorized IP tracking can destroy trust and lead to reputational damage, especially if it results in data breaches or other privacy violations.

How to protect your IP address

Protecting your IP helps safeguard your privacy, prevent cyberattacks, and reduce tracking by advertisers or malicious actors. Fortunately, there are several effective ways to secure your IP and maintain control over your digital footprint. 

Use a VPN to mask your IP (recommended)

A VPN (Virtual Private Network) is one of the most effective ways to protect your IP address. By routing your internet traffic through a secure server, a VPN hides your real IP and replaces it with one from its own network.

With ExpressVPN, you can choose to connect to a server in a different country, making it appear as if your IP is located there. Anyone monitoring your activity can only see the VPN’s IP address, not yours. This helps to protect your privacy by preventing others from spying on your real location or tracing your online activity back to your digital profile. 

A VPN also encrypts your online traffic, creating a secure tunnel that prevents outsiders from seeing your online activity, including hackers, advertisers, and even your ISP.

Getting started is simple:

1. Subscribe to ExpressVPN.
2. Download the app on your preferred device.
3. Press the “On” button to activate your VPN.

When you visit websites, post comments, or send emails, the IP address visible to others will belong to ExpressVPN, shared by many users for added anonymity. This makes it nearly impossible to trace your activity back to you, even on public Wi-Fi.

Enable firewalls and use secure networks 

Firewalls are an essential tool for protecting your IP address and network. They act as a barrier between your device and potential intruders, blocking unauthorized traffic from accessing your system.

Modern firewalls block suspicious activity while still allowing legitimate web traffic. This ensures you can browse the internet and use applications without compromising your security. Configuring your firewall properly is key—while a “deny all” rule offers maximum protection, it requires careful setup to avoid blocking legitimate connections.

In addition to firewalls, using secure networks is equally important. Avoid public Wi-Fi when possible, as it’s easier for hackers to intercept traffic and trace your IP address on unsecured networks. Instead, stick to trusted networks with strong passwords and updated security protocols.

Regularly update your router and devices

Keeping your router and devices updated is crucial for protecting your IP address and securing your network. Manufacturers regularly release firmware updates to fix vulnerabilities and enhance security features. Neglecting these updates can leave your router exposed to threats like Heartbleed, Krack, Poodle, and ZuoRaT, which hackers can exploit to gain access to your network.

Updating your router ensures you have the latest cybersecurity tools to guard against these risks. If your router is outdated or no longer receives updates, consider upgrading to a modern VPN router. A VPN router sends all your internet traffic through a secure server, automatically masking your IP address and protecting every device connected to your network.

Regular updates for your other devices, such as smartphones, laptops, and smart home gadgets, are equally important. These updates often include patches for security flaws that could otherwise be exploited to track or compromise your IP address.

Avoid clicking on unknown links

Clicking on suspicious or unknown links can expose your IP address to hackers or trackers. Many of these links use tools like IP grabbers to get your IP address, ISP, and approximate location as soon as you click.

These links are often disguised as harmless messages, promotions, or offers, making them easy to fall for. Once your IP address is exposed, attackers can use it for activities like targeted phishing, tracking, or even launching cyberattacks.

Make sure you only click on links from trusted sources. Be cautious of links sent via email, social media, or messaging platforms that seem too good to be true or are unsolicited.

Use browser privacy features

Modern browsers have privacy features that can help protect your IP address and reduce online tracking. These tools are designed to limit the amount of information websites and advertisers can collect about you during your browsing sessions.

Key features to enable:

• Private browsing or incognito mode: Prevents your browser from saving your search history, cookies, and temporary files. While it doesn’t hide your IP address, it minimizes local tracking on your device.
• Tracker blocking: Many browsers now offer built-in tools to block trackers and third-party cookies, which advertisers use to monitor your activity.
• VPN extensions: Adding a VPN extension like the ExpressVPN Chrome extension masks your IP address by routing your traffic through a secure server. This hides your location and encrypts your data, providing real-time privacy while you browse.

What to do if someone has your IP address

If you suspect your IP address is exposed or being misused, there are practical steps you can take to protect yourself and minimize potential risks.

Contact your ISP

One of the first steps you should take is to contact your ISP. ISPs assign and manage your IP address, so they can help you address any concerns or take further action.

What your ISP can do:

• Investigate misuse: They can check if your IP address has been flagged for suspicious activity, such as spamming or unauthorized access attempts.
• Provide a new IP address: In many cases, your ISP can issue you a new dynamic IP address to replace the exposed one, minimizing the risk of further exploitation.
• Offer additional guidance: Your ISP may provide advice or tools to enhance your network security, such as enabling features like firewalls or monitoring unusual traffic.

Change your IP address

If you suspect someone has your IP address, changing it is an effective way to prevent further risks to your privacy. You can do this in one of two ways:

• Restart your router: For most users with a dynamic IP address, restarting your router can assign you a new one. Simply turn off your router, wait a few minutes, and turn it back on. If your IP doesn’t change, try leaving it off overnight.
• Request a new IP from your ISP: If restarting your router doesn’t work or you’re using a static IP, contact your ISP directly. They can assign a new IP address to your account or guide you through the process of switching to a dynamic IP.

For added protection, consider using ExpressVPN. Our VPN masks your IP address, preventing it from being exposed in the first place. Instead, you can choose a VPN server from locations all over the world to switch your IP address and keep your real one hidden. That way, websites and online trackers only see the VPN server’s IP address, not yours. 

ExpressVPN’s ShuffleIP feature further enhances your online privacy by assigning a different IP address for each website you visit. This dynamic IP allocation makes it exceedingly difficult for digital spies to track your activities or build a profile based on your browsing habits.

Strengthen your network security

Hackers often exploit weak network defenses to target exposed IP addresses, so securing your network is a critical step for stopping it from falling into the wrong hands.

Here’s how you can strengthen your network:

• Change default settings: Update the default username and password on your router to a strong, unique combination. Default settings are easy targets for attackers.
• Enable WPA3 encryption: Ensure your Wi-Fi is secured with a strong encryption protocol, such as WPA3, which offers higher protection than older standards like WPA2.
• Enable your router’s firewall: Many routers come with built-in firewalls that can block unauthorized traffic. Activating this feature adds an extra layer of security.
• Use a VPN router: For comprehensive protection, consider upgrading to a VPN router, which automatically encrypts all traffic and hides your IP address for every device on your network.

Monitor unusual activity on your network

Keeping an eye on your network traffic is essential for detecting potential misuse of your IP address. Unusual activity could indicate that someone has your IP address and gained access to your network. 

Watch out for these signs of suspicious activity:

• Unexpected devices: Check your router’s admin panel for unfamiliar devices connected to your network.
• Spikes in data usage: A sudden increase in your internet usage could suggest unauthorized activity, such as a botnet using your IP address.
• Frequent slowdowns: Persistent lag or reduced internet speeds might mean your network is being exploited.

Most modern routers and network monitoring tools allow you to track connected devices and data usage, so refer to your router manual if you’re unsure how to do this.

Seek legal assistance if necessary 

If someone is using your IP address in serious ways, it might be time to seek legal assistance—especially if you suspect hacking attempts, online harassment, or illegal activity. 

Here are some steps to take:

• Document evidence: Keep records of any unusual activity, such as unauthorized access attempts, threatening messages, or notifications of misuse tied to your IP address.
• Contact local authorities: Law enforcement can investigate and take action against offenders in cases of cyberstalking, harassment, or other malicious activity.
• Consult a cybersecurity expert: A professional can help you understand the extent of the issue and suggest ways to mitigate the damage.
• Involve a lawyer if needed: For severe cases, legal counsel can guide you on pursuing legal action, particularly if damages or defamation are involved.
