Your public IP address is the internet-facing address assigned by your network provider. Websites and APIs use it to know where to send traffic back to your device.
IPv4 is the older format with dotted numbers such as 203.0.113.10. IPv6 is newer, longer, and designed to support a much larger number of unique addresses.
Location details shown here are approximate and come from free IP geolocation data. They are helpful for troubleshooting, but they are not precise enough to identify an exact street address.
How to use
Knowing your public IP address is useful for troubleshooting, hosting, remote work, VPN checks, DNS updates, firewall rules, and general network diagnostics. This tool shows the address in a large format so it is easy to copy, while also adding location and provider context when the lookup service returns those details. Everything runs in the browser and requires no account or sign-in.
It is important to remember that IP-based geolocation is approximate. The city, region, and ISP data shown here can be very helpful for diagnostics, but they are estimates based on IP ranges rather than exact GPS coordinates. Even so, the combination of IP, timezone, and provider information is often enough to confirm whether a connection appears local, remote, tunneled, or unexpectedly routed through another network.
