Developer & Web
See the IP address our server sees, the rough location attached to it and what your browser sends.
This tool asks our server to perform the lookup. What you enter is used for that request only and is not stored. How privacy works
Shows the public IP address your connection is using - the one every website you visit sees - along with the headers your browser sent with the request.
The location beside it comes from an IP database at the edge of our network. It is approximate: a VPN, a mobile carrier or a company proxy can place you in another city or another country entirely, and city-level guesses are often wrong. It is not your device's GPS position.
Our server answers the question, because only the server can see the address the request arrived from. Nothing is logged or stored.
