What the web can see

A hands-on lesson in web visibility: what many sites can learn from your browser, what this server sees after your network path, and how that compares to optional signals (location, media, WebRTC). Use it to understand VPNs, proxies, and privacy settings—on your own devices only.

        Compare the address the site infers with the sections below. Differences often illustrate VPN routing, NAT, corporate proxies, or how your reverse proxy forwards client IP headers.

WebRTC and your public address Lesson

      

        WebRTC can reveal network paths that differ from a simple “what is my IP” page. This short exercise gathers ICE candidates so you can compare them with the server section above—common when learning how VPNs and browsers handle UDP.

        IP location lookups may be sent to a third-party service from this server; check their privacy policy if that matters to you. Operators can switch to an on-server database for stricter control.
