Your public IP address, as seen by this site
Your router has one public address that every device in the home or office shares on the internet. Inside, devices use private addresses — 192.168.x.x, 10.x.x.x or 172.16–31.x.x — which can’t be reached from outside. This page shows the public one, which is what websites and mail servers see.
If your provider supports IPv6, your browser may prefer it, so you’ll see a long address with colons instead of four numbers. Both are normal; many connections have one of each.
The location is estimated from the provider’s registration data, so it often shows the provider’s hub city rather than your town. With a VPN, iCloud Private Relay or a company proxy, you’ll see their exit point instead.
Most home connections get a dynamic address that can change when the router restarts or from time to time. Businesses usually ask for a static IP, which is needed for things like firewall allow-lists, remote access, VPN servers and mail servers.
