What this tool does
Reads your connection's public-facing IP address directly from the request itself, so the result reflects your actual public IP rather than a cached or stale lookup. It also shows the ISP or hosting organization associated with that address and an approximate geographic location, sourced from a public IP geolocation database.
Why this matters
Your public IP is what every website, server, and service you connect to sees — it's the address used for outbound traffic once your router or ISP applies NAT. Knowing it is the first step in troubleshooting remote access issues, allow-listing your connection on a firewall or VPN, or confirming a VPN is actually routing your traffic.
Why is my IP different from what my router shows?
Your router's WAN IP is usually your actual public IP as assigned by your ISP — but if you're behind a VPN, corporate proxy, or carrier-grade NAT (CGNAT), what this tool sees is whatever's making the outbound request on your behalf, which can differ from your router's own WAN address.
