WebRTC Leak Test

Gather WebRTC candidate addresses in the browser to check whether a non-exit public IP is leaked.

What is WebRTC?

WebRTC (Web Real-Time Communication) is a browser capability for audio, video and peer-to-peer data. It gathers network candidates while establishing a connection.

What is a WebRTC leak?

If a public candidate differs from your current exit IP, VPN or proxy coverage may be incomplete, or traffic may be split. This tool checks public candidates only and does not treat mDNS-masked local addresses as leaks.

How should I read the result?

A matching address is not an absolute guarantee for every environment. No candidate found does not mean no leak: browser restrictions, extensions or the network may have blocked discovery.

What to do if an address leaks

Enable WebRTC/IPv6 leak protection or full-tunnel mode in the VPN and retest after reconnecting. Firefox users can review media.peerconnection privacy settings. On Chromium browsers, prefer protection supplied by the browser or VPN vendor and avoid untrusted extensions.
