WebRTC Leak Protection: Hiding Your Real IP in Browsers

WebRTC IP Leaks

WebRTC can expose your real IP even when using a proxy.

TL;DR: WebRTC for video/audio can bypass proxies. Disable it or use extensions to prevent leaks.

What is WebRTC?

WebRTC enables:

Video/audio calls in browser

P2P file sharing

Screen sharing

It needs your real IP for direct connections - which can leak.

Chrome

Use extensions:

uBlock Origin (with proper settings)

Most handle WebRTC properly per profile.

Best Practice

Disable WebRTC unless you need it. Test for leaks regularly, especially before sensitive operations.
