WebRTC Leak Test

Comprehensive WebRTC leak detection including VPN/Proxy leaks, local IP exposure, and mDNS obfuscation analysis.

What This Tool Does

Our WebRTC leak test checks if your browser's WebRTC implementation reveals your real IP address. WebRTC is a technology used for video calls and peer-to-peer communication, but it can bypass VPNs to expose your true local and public IP addresses. This test identifies any IP addresses exposed through WebRTC, helping you verify your privacy setup.

Common Use Cases

Verify VPN protection isn't bypassed by WebRTC
Check browser privacy settings effectiveness
Test browser extensions that claim to block WebRTC
Audit your privacy setup before sensitive browsing
Debug video call connectivity issues

Frequently Asked Questions

What is a WebRTC leak?

WebRTC can expose your real public and local IP addresses directly through browser APIs, bypassing VPN tunnels. This happens because WebRTC was designed for peer-to-peer communication and needs to discover your real network addresses to establish connections.

How do I prevent WebRTC leaks?

Disable WebRTC in browser settings (Firefox: about:config → media.peerconnection.enabled = false), use browser extensions like uBlock Origin or WebRTC Leak Prevent, or use browsers like Brave that block WebRTC leaks by default.

Will disabling WebRTC break websites?

Disabling WebRTC may affect video conferencing (Zoom, Google Meet, Discord), voice calls in browsers, and some file sharing features. You can use selective blocking to allow WebRTC only on trusted sites.
