What is a public IP address?

Your public IP address is the address assigned to your internet connection by your ISP. It is visible to every server and website you connect to, and is used to route traffic back to your device.

What is the difference between IPv4 and IPv6?

IPv4 addresses use four groups of numbers separated by dots (e.g. 203.0.113.42). IPv6 is the newer standard using eight groups of hexadecimal values separated by colons. Both can identify your internet connection.

Why does my IP address show a different city than where I am?

IP geolocation is approximate. Your ISP may route traffic through a regional hub in a different city, and the geolocation database may lag behind ISP network changes. VPNs also change the apparent location.

Does this tool store my IP address?

No. Your IP is only used to display information to you. It is not logged or stored.

Why would I need to know my IP address?

Common reasons include configuring firewall allowlists, setting up remote desktop access, troubleshooting network connectivity, or providing your IP to a server administrator for access control.

What is an ISP and ASN?

ISP stands for Internet Service Provider: the company that provides your internet connection. ASN (Autonomous System Number) is a globally unique identifier assigned to each network on the internet.

Does using a VPN change my IP address?

Yes. When connected to a VPN, the IP address shown here will be the VPN server's public IP, not your own.
