WebRTC Leak Test
Inspect the addresses exposed by your browser during WebRTC connection setup.
Inspect WebRTC addresses
The test creates a temporary peer connection and contacts a STUN server. Modern browsers may replace local addresses with mDNS names, so a clean result is useful evidence, not proof that every application is leak-free.

How to interpret the test
A server-reflexive address that differs from the public VPN address can indicate a leak. A .local host candidate means the browser masked the local address with mDNS. Browser results do not test native apps or DNS traffic.
