United States (US)What is my IP number?
Your IP number, or IP address, is the public address your internet provider gives your connection. Every website, app and online service you use sees it, because it is where they send their replies. The number shown at the top of this page is your public IP: the one the rest of the internet sees for your home or office network, shared by every device behind your router.
Inside your network, each phone, laptop and TV also has a private IP such as 192.168.1.20, which only your router knows. Websites never see it. Read more in our guide to public vs private IP addresses.
IPv4 and IPv6
An IPv4 number looks like 203.0.113.42: four numbers from 0 to 255. Because there are only about 4.3 billion of them, providers increasingly also give you an IPv6 address, a longer hexadecimal number such as 2001:db8:85a3::8a2e:370:7334. This page checks both. If IPv6 shows "Not detected", your provider or router has not enabled it yet; test it fully with the IPv6 test.
How accurate is the location?
The location comes from IP geolocation databases, which link address blocks to the place where a provider uses them. The country is almost always right; the city is often the nearest large town or your provider's hub, and can be tens of kilometres away. Your IP number never reveals your street address. See how accurate IP geolocation is, or locate any other address with IP to geolocation.
Does my IP number change?
Most home connections have a dynamic IP that changes from time to time, for example when the router restarts. Mobile data usually changes it even more often. Businesses that host servers or need remote access often pay for a static IP. A VPN replaces the IP websites see with the VPN server's address; check it is working with the WebRTC leak test.

Frequently asked questions
Is my IP number the same as my IP address?
Yes. "IP number" and "IP address" mean the same thing: the numeric address of your connection on the internet.
Can someone find me with my IP number?
Not your home address. An IP number shows your provider and an approximate area. Only your provider can link it to an account, and usually only for the police with a legal order.
Why is the location shown in another city?
Geolocation databases record where your provider's network is registered or routed, which is often a nearby city or a regional hub, not where you are.
How do I hide my IP number?
Use a VPN, a proxy or the Tor Browser. Websites then see that service's IP instead of yours. Our guide on how to hide your IP address compares the options.
Why does my IP number differ on Wi-Fi and mobile data?
Each connection comes from a different provider network, so each gets its own public IP number.
