What is What Is My IP?
Your public IP address is the identifier your router presents to the rest of the internet. Every site you visit, every server you connect to, sees this address — not the private 192.168.x.x or 10.x.x.x address assigned to your laptop or phone on your home network.
This page detects that public-facing address the moment it loads, for both IPv4 and IPv6 if your connection supports both, and pairs it with geolocation (country, region, city), your Internet Service Provider, the organization the address is registered to, and its Autonomous System Number (ASN).
