WebRTC Inspection

Public IP (STUN)probing
WebRTC can expose your internal LAN address (e.g. 192.168.x.x) to any website you visit, even behind a VPN. This is often unexpected.

About this page. All data above is collected passively in your browser. No port scans, no probes against your network, no third-party trackers. Nothing is stored or transmitted to us beyond the standard request log any web server keeps. The point isn't to alarm you — it's to show what's routinely exposed by any connection, and what an attentive engineer notices when designing a network.
