What's my IP address?

It's the address the internet uses to send data back to you. The one shown above is your public IP address, the one every website and service you connect to can see. Your internet provider assigns it, and your router shares it between all the devices on your network.

IPv4 addresses are four numbers, like 203.0.113.42. IPv6 addresses are longer and written in hexadecimal, like 2001:db8::1. Many connections now have both, so this page shows each one separately with its own copy button.

No. Addresses such as 192.168.x.x or 10.x.x.x are private to your home or office network. To see your local address, run ipconfig on Windows or ip addr on Linux, or look in your network settings on macOS.

Only roughly. It usually points to your internet provider and a nearby city, not your street address. If you use a VPN, sites see the VPN server's address and location instead of yours.

Most home broadband and mobile providers assign dynamic addresses. They can change when your router restarts or when your provider reassigns them. A fixed (static) IP is usually a paid extra.

Run curl justmyip.dev to get just the address, or curl justmyip.dev/json for location and network details. In PowerShell, use irm justmyip.dev.
