WebRTC Leak Test
Inspect ICE candidates, classify host/srflx/relay, mDNS and public/private addresses, with an optional STUN comparison against the server-visible IP.

The external STUN test contacts a public STUN server only after explicit action. Neither test activates camera or microphone.
Measurement details
Search a property, or expand only the group you need.
Start with the local check; it will not request camera or microphone permission.
Camera and microphone are never activated automatically. ICE results stay in the page.
Usage and result interpretation
- Start locally and opt into the external STUN check if needed.
- Inspect ICE types and addresses; no public address does not prove leak resistance.
The check is local; optional STUN comparison may initiate a network connection.
How to use WebRTC Leak Test
Inspect ICE candidates exposed by WebRTC, including host, server-reflexive, relay and mDNS signals. Compare them with the server-visible address.
Understanding results and limitations
Browsers may mask local addresses using mDNS, and optional STUN checks depend on current network policies and connectivity.
