What the internet can see about your connection

Every website you open receives the facts on this page — they travel with the request. They are also read here, in your browser, by this page itself. We run no fingerprinting test, set no tracking cookie for it, and store none of it. The point is simply to show you what a server starts with.

How much does that narrow things down?

The honest answer is: less than people fear, more than nothing. An address is usually shared — with everyone behind the same router, the same mobile tower, the same VPN exit or the same office — so it identifies a connection, not a person. What makes a visitor recognisable is not one item but the combination: the same address plus the same browser string plus the same screen and time zone is a much smaller group than any one of them alone. We show you the combination rather than scoring it, because a score would be made up.

What we deliberately do not do

• No canvas, WebGL, audio or font fingerprinting, and no probing of what you have installed.
• No cross-site cookie, no third-party tracking pixel of our own, no visitor id kept on the server.
• No storing of the lookup history against your address — see the privacy policy.
• The watchlist and passport keep their lists in your browser, so they have nothing to store on our side.

If you want less to be visible

In rough order of how much they change the picture, and each with its own cost:

• Use a VPN or Tor — your address becomes the provider's or an exit node's. Tor hides it from us but is slow and some sites block it; a VPN just moves the trust to the provider, who then sees what your ISP used to see.
• Turn on Do Not Track / Global Privacy Control in your browser. It is a request, not a guarantee: we honour it, others may not.
• Block third-party cookies and trackers. That is what most of the "you are being followed" feeling actually comes from, and it is a browser setting rather than anything about your address.
• Rotate your address if your provider allows it — reconnecting a router usually does it, and it costs nothing.

This page is educational, not a scan: it reports what already arrived with your request and what your browser tells any page. It cannot find your name, your exact position or anything about your device beyond the browser string above.
