What Can Someone Do with Your IP Address? Risks and Privacy Tips

Your IP address might seem insignificant, but it’s a key part of your online identity. When you browse the internet, join a video call, or open an app, your IP address is visible to the service you’re using. Because of this, some people prefer not to have their real IP directly tied to their online activity.

So, what can someone do with your IP address? That often depends on what other information they have about you. On its own, your IP address can reveal your general location and your internet service provider, and it may also be used to target your network with attacks such as DDoS attempts.

What Is an IP Address?

An IP address is like your network’s postal address on the internet; it’s a string of numbers that uniquely identifies the device or network you’re using. You can see your IP address here.

There are two main types of IP addresses: public and private. Your public IP is the one the outside world sees. It’s assigned by your ISP and is visible to websites, apps, and pretty much anyone you connect to online.

Your private IP, on the other hand, stays hidden within your home or office network. Only devices within that network, such as phones, laptops, or printers, can see and use it to communicate with each other.

How Can Someone Find My IP Address?

Your IP address is your identifier, and as such, any service or device you communicate with can see it. Here’s how people can get their hands on your IP address:

• Visiting a website: Site owners automatically log visitor IPs and usually store them. That means anyone who accesses a website’s server can potentially see your IP.
• Clicking on ads or links: Digital marketers often collect IP addresses for analytics and retargeting purposes. Cybercriminals sometimes use malicious ads and links to harvest IPs and other personal information.
• Using social media: Most social media platforms collect some personal information, including your IP address.
• Playing online games: Peer-to-peer games and those hosted on private servers use your IP address to identify you and allow or deny access to certain domains. Game server admins can access these logs to see your IP address.
• Accessing forums or chatrooms: Online forums usually log user IP addresses so that admins can see information about who’s posting – and ban you if you break the rules.
• File sharing: Sending and downloading files via P2P networks (e.g., for open source projects) reveals your IP address to the person you’re sharing files with and potentially anyone in that P2P network.
• Social engineering: Cybercriminals pretending to be someone else could trick you into clicking on a malicious link that can be used to uncover your IP address.

What Does an IP Address Tell You?

Note: The additional details shown by an IP lookup tool vary depending on the service you use.

While it won’t give away your name or exact street address, your IP address can point to your approximate location (e.g., the city, postal code, or region you’re in). That’s because ISPs must register the IP addresses they acquire with a public database which requires them to disclose their business address and the geographic region the IP is intended to serve.

This means your IP can also hint at who your ISP is and what type of device or network you’re using (like mobile vs broadband). Your network setup can even give someone who wants to know information about whether you’re part of a larger organization or institution.

Websites, apps, and advertisers often use this information to customize content, enforce location-based restrictions, and build a digital fingerprint that follows you across the web. So while your IP isn’t a full ID card, it still plays a role in identifying online activity.

What Can Someone Do with My IP Address?

On its own, an IP address doesn’t reveal much. Still, that doesn’t mean it’s safe to share it with everyone. In the wrong hands, and when combined with other data, your IP can become a useful tool for tracking, profiling, or even launching targeted attacks.

Here’s what someone might be able to do with an IP address:

• Track online activity: Websites can trace your IP address across the internet and gather data on your browsing habits and interests.
• Deliver hyper-targeted ads: Advertisers use your IP and browsing behavior to follow you across sites and serve increasingly personalized content.
• Uncover your digital identity: Cybercriminals can cross-reference your IP with leaks and tracking data to uncover details like browsing history and device type.
• Impersonate you online: With enough data, someone could hijack your accounts, pose as you in emails, or trick others into believing they’re communicating with you.
• Impersonate your ISP to steal information: Your IP address can reveal your internet provider, giving scammers enough to pose as your ISP. They may call, text, or even show up pretending to offer tech support or collect payment, using that trust to steal personal information.
• Launch a DDoS attack: A bad actor can use your IP to flood your network with fake traffic, knocking you offline or disrupting activities like gaming or streaming.
• Exploit security flaws in your network: A visible IP allows attackers to scan your system for open ports or weak settings that can be used to break in.
• Access your devices: If someone knows your IP and the network you’re connected to is vulnerable, they could reach shared files, smart devices, or even security cameras.
• Restrict your access to content: Websites may block your IP based on location or behavior, locking you out of services or platforms.
• Sell your IP on the dark web: Stolen IPs are valuable to cybercriminals, who may use them for scams, ad fraud, or to mask illegal activity.

How to Prevent Others from Seeing or Using Your IP Address

There are several things you can do to help keep your IP address – as well as other personal information – as private as possible.

Use a Reliable VPN

A VPN hides your real IP address from any websites, apps, or services you use online. It does this by routing your internet traffic through one or more of its servers. This way, your traffic first goes to the VPN server and then to the final destination (whatever service you’re trying to reach). 

That service then sees an IP address, but the one that belongs to the VPN server – not yours. This not only hides your IP address, but can make it appear as if you’re in a different location; the IP address of the server matches the location of the server. 

Use Tor Browser

Tor (short for The Onion Router) is a free browser that routes your internet traffic through a series of encrypted servers or “nodes,” in locations all around the world. Tor hides your IP by routing your traffic through multiple nodes, so the destination website sees the IP address of the final exit node instead of yours. 

Because your traffic hops through several nodes, it’s extremely difficult for anyone to trace activity back to you or discover your real location.

Unfortunately, because your data passes through multiple relays, browsing can feel slow or clunky, and some websites block Tor traffic entirely. 

While it’s known for offering excellent privacy, it’s worth noting that the entry node (the first Tor node your connection reaches) can see your IP address. If Tor is legal in your location and you want an added layer of privacy, you can connect to PIA first, so Tor never sees your IP address in the first place.

Use a Proxy Server

A proxy server acts as a middleman between your device and the websites you visit. When you use one, your requests are routed through the proxy first, so the site you’re accessing sees the proxy’s IP address rather than yours.

Proxies can help make your location less visible and can also assist with managing network traffic. The main difference between a VPN and a proxy is that a VPN encrypts your traffic, making it much harder for anyone monitoring your network, including your ISP, to see what you do online. While most VPNs offer user-friendly apps, many proxies are tricky to configure and require some tech knowledge to set up.

Use a Dedicated IP Address

A dedicated IP address is a unique IP that’s assigned only to you.

When you use a VPN, the app automatically gives you an IP address to use from its roster. It picks one from the server location you connect to, but if you disconnect and reconnect to the same server location, you’ll get a brand new IP address from the VPN. Essentially, you’re sharing a finite number of VPN IP addresses with the rest of the VPN’s users.

If you need an IP address that doesn’t change for work setup or running a personal server, PIA offers Dedicated IPs in a range of locations across 10 countries, assigned using an anonymous token-based system, so even PIA doesn’t know what IP address you get, helping to protect your real identity. 

Update Your Firewall and Router

Keeping your firewall and router firmware up to date helps close security gaps that attackers could exploit to uncover your IP address. It also ensures your network is protected against the latest threats and scans for suspicious activity.

While this doesn’t actually hide your IP address, it does reduce the risk of someone using it to breach your home network.

Practice Good Cyber Hygiene

Following good cyber hygiene makes it much harder for someone to misuse your IP. Avoid clicking on suspicious links, especially from unknown emails or messages. Use strong, unique passwords, enable two-factor authentication, and keep your devices and apps updated. Also regularly review your privacy settings on social media and avoid oversharing personal information that could be used to trace your location.

What to Do If Someone Has Your IP Address

You don’t need to panic if your IP address has been exposed online, but you should take action to reduce the risk of it being misused. Here are some actions to consider if you’re concerned about how someone might use your IP address:

• Restart your modem or router. In most cases, this requests a new dynamic IP from your ISP, but it won’t change a static IP address.
• Check your firewall and router settings to close any unnecessary ports and disable remote access.
• Scan your network for intrusions or unfamiliar devices using security software.
• Avoid clicking suspicious links that might expose your IP again.
• Use a secure VPN to mask your IP address going forward.
