Your public IP address is what every website you visit sees. This page shows it back to you, together with the approximate location and network it maps to, and the browser details that are sent along with every request.
IP geolocation looks up which block of addresses your provider registered and where they said it is used. That can be a regional hub rather than your town, and on mobile networks it is frequently a different city entirely. Behind a VPN it shows the exit node. City-level accuracy is the realistic ceiling, and even that fails often.
The address shown here is your public IP - assigned by your provider and shared by every device on your network through NAT. Your device also has a local address, typically starting 192.168. or 10., which only exists inside your own network and cannot be reached from the internet.
The panel below shows a handful of the values sent or readable on every page load. Combined - language, time zone, screen size, fonts, rendering quirks - they often identify a browser uniquely even with cookies disabled. That is browser fingerprinting, and unlike cookies there is no button to clear it.
IP geolocation resolves to the network operator's registered location, which can be a different city or even country from yours. Mobile networks and VPNs make it less accurate still. City-level accuracy is typical at best.
Your public IP is assigned by your provider and is shared by every device on your network. Your local IP - usually starting 192.168 or 10. - identifies your device inside your own network and is not visible from the internet.
