WebRTC Leak Test

WebRTC can expose your real IP even when you're using a VPN. This test runs entirely in your browser to find any IPs your browser would reveal.

What we test

Your browser uses WebRTC for peer-to-peer video and audio calls. To establish a connection, it needs to discover your IP addresses — including ones that bypass your VPN tunnel. We trigger that discovery and report what we find.

Modern browsers obfuscate local IPs as .local mDNS hostnames by default, but public IPs may still leak.
