What's My IP

Your connection at a glance

The tool shows the public IPv4 and IPv6 address the internet sees for you, the provider and rough location behind each address, its reverse DNS hostname — and the DNS resolvers that look up domain names for you.

How it works

• IPv4 / IPv6 — your browser contacts one server that is reachable only over IPv4 and one that is reachable only over IPv6. Whichever answers shows the address you used. “No connection detected” means your network does not offer that protocol.
• DNS resolvers — your browser loads a few random, never-before-seen subdomains. Their name server records which resolvers asked for them. Providers often run a pool of resolvers, so several addresses are normal.
• Reverse DNS — the hostname comes from a PTR lookup over DNS-over-HTTPS.

If you use a VPN or your browser’s “secure DNS” (DNS-over-HTTPS), you see the VPN’s or the DoH provider’s servers — which is exactly what this test is for: checking that DNS requests do not leak past the VPN.

Privacy

The test runs entirely in your browser; this site stores nothing. To work, your browser talks to ipleak.net (addresses, provider, DNS detection) and to Cloudflare’s DNS-over-HTTPS service (reverse DNS). Both see your IP address as part of those requests. Content blockers that block ipleak.net stop the test.
