What Is My IP Address? (And How to Hide It)

Your IP address is the number the internet uses to send data back to you. Every time you load a page, your device's public IP travels with the request so the server knows where to send the response. It is a bit like the return address on an envelope: necessary for delivery, but it also reveals more than most people expect. You can see your own address with the What Is My IP tool, and look up the details of any address with the IP Information tool.

A public IP address exposes a few things at minimum. It reveals your approximate location, usually your city or region, derived from databases that map IP ranges to areas. It is not GPS-accurate and will not show your street address, but it is enough to localize you. It also reveals your ISP or hosting provider, the company that owns the address block, and the autonomous system (ASN) the address belongs to.

What it does not reveal is just as important: your name, your exact home address, or what is on your screen. The location is an estimate, and the ISP is the registered owner of the address, not you personally. Only your ISP can link a specific address to a subscriber account, and they require legal process to disclose it.

You actually have two kinds of address. Your public IP is the single address your whole home or office network presents to the internet. It is assigned by your ISP and is what websites see. Your private IP is the address your router hands out to each device behind it, such as your laptop, phone, and TV. Private addresses live in reserved ranges like 192.168.x.x, 10.x.x.x, and 172.16 through 172.31.x.x, and they are invisible to the outside world.

Your router performs NAT (Network Address Translation) to share one public IP among all your private devices. So when a tool shows "your IP," it is showing the public one your network presents, which every device in your house shares. This is why the What Is My IP tool shows the same address whether you check from your phone or your laptop on the same Wi-Fi.

IPv4 addresses look like 203.0.113.42, made of four numbers from 0 to 255. There are about 4.3 billion of them, and the world ran out of fresh allocations years ago. IPv6 addresses look like 2001:0db8:85a3::8a2e:0370:7334, much longer and effectively unlimited. Many networks now give you both at once.

If a tool shows you an IPv6 address, that is normal and increasingly common. If you need to work with IPv6 notation, the IPv6 Compress tool shortens an address to its canonical form and the IPv6 Expand tool writes it out in full. Seeing a different IPv6 address than a friend on the same site is also normal, since IPv6 privacy extensions rotate the address your device uses.

There are several legitimate reasons to mask your address. You might want to stop websites and advertisers from profiling you by location, avoid bandwidth throttling tied to your IP, access content restricted to certain regions while travelling, or keep your home IP out of forum posts, game lobbies, and other public places where it could be logged.

Hiding your IP is legal in most countries, where VPNs and proxies are common and widely used. What you do online is still subject to the law, but the act of masking your address itself is not the issue.

There are three real methods, in order of how much they protect you. A VPN is best for most people: it routes your traffic through its server, so websites see the VPN's IP rather than yours, and it encrypts the traffic between you and the VPN. The Tor Browser is best for anonymity, bouncing your traffic through several volunteer relays so it is very hard to trace, at the cost of speed. A proxy is the lightest option, rerouting a single app's traffic and changing the visible IP but usually without encryption.

You can also change rather than hide your IP. Many home connections use dynamic addresses that rotate periodically, so restarting your router for a while, or asking your ISP, may give you a new one. After connecting a VPN, confirm it is actually working with the VPN & Proxy Detection tool, which should show the VPN's IP and not your real one.

A VPN only helps if nothing slips around it, and two common leaks defeat the purpose. A DNS leak happens when your DNS queries go to your ISP instead of through the VPN, quietly revealing the sites you visit. Test for it with the DNS Leak Test checker. A WebRTC leak happens when your browser exposes your real IP to websites through WebRTC even while a VPN is connected. Test for it with the WebRTC Leak Test tool.

If either test shows your real IP, or your ISP's DNS servers, while you are connected to a VPN, fix that before relying on the VPN for privacy. A VPN that leaks is giving you a false sense of security rather than real protection.

Can someone find my home address from my IP? No. They can estimate your city or region and identify your ISP, but not your street address. Only your ISP can link an IP to an account, and that requires legal process.

Does turning on a VPN make me completely anonymous? No. It hides your IP and encrypts traffic, but you can still be tracked by cookies, browser fingerprinting, and the accounts you log into. Check for DNS and WebRTC leaks too, using the DNS Leak Test and WebRTC Leak Test tools.

Why does my IP address keep changing? Most home connections use dynamic IPs that the ISP reassigns periodically. A static IP stays fixed and usually costs extra. You can confirm your current address any time with the What Is My IP tool.

Is it legal to hide my IP? In most countries, yes. VPNs and proxies are legal and widely used. What you do online is still subject to the law, but masking your address is not itself illegal.
