What's my IP address?
This is the address every website sees when you visit, together with what it says about your network and location.

What an IP address is
An IP (Internet Protocol) address is the number that lets data find its way back to you across the internet. Your internet provider assigns your home connection a public IP address, and every website you visit receives it, because without it the site can't send the page back. Phones on mobile data get one from the carrier, often shared with many other customers.
IPv4 addresses look like 203.0.113.42. The newer IPv6 addresses look like 2001:db8::1. Many connections have both, and which one a site sees depends on your network and the site.
What your IP address reveals
- Your network. Every IP belongs to an autonomous system (the AS number above), which names the internet provider, mobile carrier, company or hosting firm that controls it.
- An approximate location. IP location databases map addresses to a country, often a region, and sometimes a city. Usually that's where your provider routes traffic, not your street, and it can be wrong by hundreds of miles.
- Whether you share an address. Sites can link visits from the same IP, which is one way advertisers and fraud systems connect activity across sites.
Your IP address doesn't reveal your name or street address by itself. Your internet provider knows which customer had which address and when, and can be required to say so by a court order or a legal request where you live.
What changes when you use a VPN
With a VPN on, websites see the VPN server's IP address instead of yours, so the network shown above becomes the VPN's hosting provider and the location becomes the server's. Your internet provider can then see that you are connected to a VPN, but not which sites you visit. If this page still shows your home provider while your VPN is on, your traffic isn't going through the tunnel. Try the WebRTC leak test and read our leak test guide.
The time-zone line above compares your device's clock with the time zone the IP suggests. A mismatch is normal on a VPN, and some sites use it as one signal that a visitor is on one.
What we do with your IP
Nothing beyond showing it to you. The page asks our server, which runs on Cloudflare, to read the address your request came from and the network data Cloudflare attaches to it. We don't log or store it. See our privacy policy.
Questions people ask
Can someone find my home from my IP address?
Not directly. IP location is usually accurate to a city or region at best. Your internet provider knows which customer used an address, and can be legally required to disclose it, but a website or another person can't look that up.
Why does my location look wrong?
IP location databases map addresses to where a provider registers or routes them. Mobile carriers and some providers route traffic through a city far from you, and databases go out of date.
Does my IP address change?
Most home connections get a dynamic address that changes from time to time, for example when the router restarts. Mobile connections change often. Some business plans have a fixed (static) IP.
