What is a WebRTC Leak?
Think of WebRTC as a secret agent inside your browser. Its job is to make things like Google Meet or Discord run fast by connecting you directly to other people. To do this, it needs to find the fastest "road" to your computer. Unfortunately, it often bypasses your VPN and shouts your real IP address out loud. Websites can hear this shout and know exactly where you are, even if your VPN says you are in another country.
Why doesn't my VPN block this?
Most VPNs only encrypt your internet traffic. They don't always control the internal commands of your web browser. AirOI Checker acts like a detective to catch these sneaky commands and show you if your real IP is being exposed.
How to fix a WebRTC Leak
If our tool shows your real IP address, don't worry! You can plug this hole easily:
-
Firefox: Type
about:configin the bar. Search formedia.peerconnection.enabledand double-click it to set it to False. -
Chrome/Edge: These browsers don't have an off-switch. You should install the "uBlock Origin" extension and check "Prevent WebRTC from leaking local IP address" in settings.
-
Brave: Brave blocks this by default! Just make sure your Fingerprinting protection is set to Standard or Strict.
Frequently Asked Questions
Is my local IP (192.168.x.x) dangerous?
Not really. Your local IP only shows the address of your device inside your house. It doesn't reveal your city or name. However, your Public IP is the one you must hide.
Will turning off WebRTC break websites?
It might break browser-based video calls like Google Meet or Zoom Web. If you need to use those, just turn WebRTC back on temporarily or use the dedicated app.
How often should I test for leaks?
Every time you update your browser or switch to a new VPN. AirOI Checker is always here to give you a free privacy audit.
