ip.oxmo.org answers a single question: what your public IP address is, and what it gives away. Everything else follows from it — where it appears to come from, who operates it, what network path leads to it, and what your browser says about you without telling you.

No external resources

This site loads nothing from anywhere else: no remote fonts, no CDN, no mapping library, and above all no map tiles. The map is a vector drawing served by this server.

That is not a technical affectation. A Google Maps or OpenStreetMap background would report every visit to the provider’s servers, along with your IP address — on a site whose whole subject is what that address reveals. The server’s content security policy forbids any external resource, which makes the promise checkable rather than merely stated.

Where the location comes from

From MaxMind’s GeoLite2 databases, stored on this server and refreshed weekly. No request ever goes out to a geolocation service.

These databases give the position the operator declares for a block of addresses. It is not your position, and the stated accuracy is often tens of kilometres. It is shown as it is, and drawn on the map: a dot without its uncertainty is a lie by omission.

Limits

These tools send real packets from this server to the target you name. The number of measurements is capped per address. Normal use never meets that cap. Any abuse will result in a permanent IP ban.
