WebRTC Leak

Is WebRTC leaking your real IP?

WebRTC can reveal network info that bypasses your proxy or VPN. We check whether your real route leaks, and what it means for account logins.

Why a WebRTC leak is dangerous

WebRTC is the browser's built-in real-time communication layer; to set up peer connections it gathers your network addresses — even when you use a proxy or VPN.

01

Bypasses your proxy / VPN

WebRTC asks STUN servers for your network address directly and can obtain a real public IP outside your proxy, making a carefully configured proxy useless.

02

Triggers multi-account linking

Once your real IP disagrees with the region your account claims, risk systems treat it as a disguise signal and trigger extra verification, throttling or linked bans.

03

Happens silently

A WebRTC leak needs no camera or mic permission — just visiting a page is enough, and most users never notice.

How to fix a WebRTC leak

The goal is to stop WebRTC from exposing a real route that disagrees with your exit IP.

  • Disable or restrict WebRTC in your browser (e.g. media.peerconnection.enabled in about:config, or an extension).
  • Use a proxy / antidetect browser with WebRTC leak protection that forces ICE through the proxy route.
  • Avoid multiple active network exits so your real adapter address can't be gathered.
  • Re-check after fixing to confirm the public address matches your exit IP.

Frequently asked questions

What is a WebRTC leak?
WebRTC is the browser's real-time communication layer. To set up connections it asks STUN servers for your network addresses, which can reveal a public IP that bypasses your proxy or VPN. When that address doesn't match your exit IP, your real route is leaking.
I use a VPN or proxy — why does it still leak?
Many proxies and VPNs only route normal HTTP traffic, while WebRTC opens its own peer connection that can take a different path and expose your real IP. Unless your tool explicitly forces WebRTC through the same route, the leak persists.
How do I disable or fix WebRTC?
In Firefox set media.peerconnection.enabled to false in about:config; in Chromium browsers use a reputable WebRTC-control extension or an antidetect browser with built-in leak protection. After changing it, re-run this test to confirm the public address now matches your exit IP.
Is exposing a local IP like 192.168.x.x a leak?
Not really. Local/LAN addresses are private and can't pinpoint you on their own, so we flag them as informational. The real risk is a public IP that differs from your exit IP — that's what reveals your true route.
Do mobile browsers leak via WebRTC too?
They can. Mobile Chrome and Safari both support WebRTC, so the same proxy-bypass risk applies. Run this test on the device and network you actually use for your accounts.
Does a WebRTC leak need camera or microphone permission?
No. Gathering ICE candidates doesn't require any permission prompt — simply loading a page can expose the addresses, which is why leaks so often go unnoticed.
