What is my IP? See your current public IPv4 address as detected by our edge, the forwarding header it was extracted from, your user agent string, and the full X-Forwarded-For chain. Useful for VPN verification, ISP diagnostics, and confirming what IP a service is seeing for you.
Your public IP is the address the rest of the internet sees, assigned by your ISP and shared by every device behind your router through NAT. It is different from the private address (something like 192.168.1.x) that your computer uses on the local network. This tool reports the public IPv4 address our edge detected for your request, so it reflects exactly what a remote server would log when you connect.
When a request passes through proxies and CDNs, the original client IP is preserved in HTTP headers rather than the raw connection, so this tool also shows which header the address came from, your user agent string, and the full X-Forwarded-For chain. That chain lists each hop the request traversed, which is useful for confirming a VPN or proxy is actually in the path and for diagnosing why a service might see a different IP than you expect. If the address shown is not your ISP's, something in front of you, a VPN, proxy, or corporate gateway, is rewriting the source.
Your public IP is the address your ISP assigns to your connection, which every website and server sees when you connect. The tool above shows the public IPv4 address our edge detected for your request.
A private IP (such as 192.168.1.5) is used only inside your local network and is not reachable from the internet. Your public IP is shared by all devices behind your router and is what external servers actually see.
X-Forwarded-For is an HTTP header that proxies and CDNs use to record the original client IP and each hop a request passed through. It lets a server behind a proxy still identify the real source address.
Most home connections use dynamic IPs that the ISP can reassign periodically or on reconnect. Connecting through a VPN or mobile network will also change the public IP a service sees.
