What this connection reveals

The same connection can present different addresses depending on how it is reached. Each row below is an independent request over a different path.

WebRTC negotiates peer-to-peer connections by asking a STUN server which addresses it can be reached on. It does this beneath the browser's proxy settings, so it can expose an address the rest of the page never sees.

Your browser is asked to resolve hostnames nobody has ever looked up before, in a zone this server answers for. Whichever resolver you are configured with has to come and ask us, which is how it identifies itself.

A torrent client is a separate application with its own routing, so the address it exposes to a swarm may differ from your browser's. This test hands you a magnet link for a file that does not exist, pointing at a tracker we run. Nothing is downloaded and no swarm is joined.

Reported by the device itself rather than inferred from the network. It is usually far more precise than an address lookup, and no tunnel affects it. Nothing is requested until you ask for it.

Inferred from the address, not measured. The true location is somewhere near this point, and often only identifies your provider's routing rather than you. The circle is the accuracy radius the database reports.
