My IP Address
See the IP address this server sees, and what the address itself says.
This is the one tool here that cannot run in your browser: only the server sees your address. It is shown to you and kept nowhere — not logged, not stored, not sent on.

Every request your browser makes carries a return address, or the answer would have nowhere to go. This page shows the one this server received, together with what can be worked out from the address itself.
It does not show a city, a provider or a map. None of that is in the address: it comes from a commercial database of who was allocated which block, and those databases are wrong often enough that presenting their guess as a fact would mislead you. Less, and true.
How it works
The address is read from the connection itself, classified against the blocks the relevant RFCs reserve, and shown back to you. Nothing is looked up and nothing is stored.
The reverse DNS name is computed, not resolved: it is the name a lookup would ask for, written the way DNS expects it — reversed, under in-addr.arpa for IPv4 or ip6.arpa for IPv6. Running the lookup is left to you, because doing it here would tie this page to the response time of somebody else's DNS server.
Frequently asked questions
Why does this page not show my city or my provider?
Because neither is contained in the address. Both come from a database mapping blocks to the organisation they were allocated to. That database is a licensed product, it goes out of date, and it is routinely wrong by hundreds of kilometres for mobile and business connections. Asking a third party on your behalf would mean sending them your address, which is worse. So the page shows what is true and stops.
Is my address logged?
Not by this page. It is read from the connection, rendered, and forgotten, and the response is marked so that no cache keeps a copy. Web server logs and the networks in between are outside our control, as they are on every site you visit.
Why is the address not the one I expected?
What you see is the address of whatever spoke to this server last. Behind a VPN it is the VPN's exit address; behind a corporate or carrier-grade NAT it is a gateway shared with everyone else on it; on a mobile network it changes on its own. The address your device holds on your own network is a different thing, and no web page can see it.
What does the scope mean?
Which reserved block the address falls in. Public means routable on the internet. Private is one of the ranges set aside for internal networks, loopback is a machine talking to itself, and shared is the block carriers use for large-scale NAT. Anything other than public usually means you reached this page through a proxy on your own network.
Good to know
- This is the only tool on the site that cannot run in your browser. A page has no way to discover its own public address, so the server has to tell it. Every other developer tool here computes locally.
- If your traffic passes through a proxy or a CDN, the address shown is the one that reached this server at the socket. Forwarding headers such as X-Forwarded-For are ignored on purpose: any client can set them to anything, so trusting them would let a visitor choose what this page reports.
