What is an IP address?
An IP (Internet Protocol) address is a unique number that identifies your device on a network, like 203.0.113.42. Your internet provider assigns one to your connection, and every website you visit uses it to send data back to your browser. The address shown at the top of this page is your current public IP.

Is my IP address always the same?
Usually not. Most home and mobile connections use a dynamic IP that can change when your router restarts or your provider reassigns addresses. Businesses often pay extra for a static IP that never changes. If your IP looks different than yesterday, that's normal behavior, not a problem.

Can someone find my home address from my IP?
No. An IP address reveals your approximate city and your internet provider, not your name or street address. Only your ISP can link an IP to a subscriber, and it only discloses that information through legal process. Websites you visit see the city-level estimate displayed on this page, nothing more precise.

Why does my IP show the wrong city?
IP geolocation maps address ranges to locations using databases, not GPS. Country accuracy is excellent, but city accuracy varies: providers often register ranges at regional hubs, and mobile or VPN traffic can exit far from where you are. A wrong city is a limitation of the method, not an error on your connection.

What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses like 203.0.113.42 and offers about 4.3 billion combinations, which the internet has outgrown. IPv6 uses 128-bit addresses like 2001:db8::1 and provides a virtually unlimited supply. Both run side by side today, which is why your connection may show either format depending on the network.

Does a VPN really hide my IP address?
Yes. With a VPN, websites see the VPN server's IP instead of yours; this page will show the VPN exit address and usually flag it. Your real IP stays visible to the VPN provider itself, so pick a trustworthy one. A VPN doesn't block cookies or browser fingerprinting: it hides your IP, not your identity.

Why is my IP different on Wi-Fi and mobile data?
Each connection has its own public IP. On Wi-Fi you go online through your home provider; on mobile data you use your carrier's network, where one address is often shared by many users (CGNAT) and IPv6 is more common. Switching networks switches your visible IP, and that's expected.
What can someone do with my IP address?
Realistically: estimate your city, identify your internet provider, and in rare cases target your connection with unwanted traffic. They can't hack your devices, read your files, or find your identity from an IP alone. Avoid posting it publicly, but remember that every website you visit already sees it.
