WebRTC Leak: Is Your VPN Lying?

Sometimes your browser talks too much. Use our WebRTC leak test to see if your real home IP address is leaking through your secure VPN tunnel.

Quick Tool Fact

WebRTC is a technology for video calls, but it has a nasty habit of "shouting" your real IP address to find the fastest connection. This bypasses your VPN, making your real location visible to any site you visit.

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:config in the bar. Search for media.peerconnection.enabled and 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.
