WebRTC Leak Test: Is Your IP Leaking?

Check if your browser is bypassing your VPN. Our WebRTC leak test probes STUN servers to see if your real Public or Local IP is visible to the world.

AI Overview

A WebRTC Leak is a security flaw that reveals your real IP address even when using a VPN or Proxy. WebRTC uses STUN servers to find your direct network path, which can bypass encrypted tunnels. Testing for these leaks is vital to ensure your online anonymity is not compromised.

What is a WebRTC Leak?

WebRTC (Web Real-Time Communication) is a technology that allows browsers to talk directly to each other for video calls and file sharing. To make this work, your browser must find its own Public IP address. Unfortunately, this process often bypasses VPN tunnels, letting websites see your real identity even if you are "protected."

Security Tip: If this tool displays your real ISP IP address while your VPN is connected, your privacy is compromised. You must disable WebRTC in your browser settings immediately.

How to Fix WebRTC Leaks

You can stop IP leaks by following these steps on ZKB Tracking:

  • Firefox: Type about:config in the address bar, search for media.peerconnection.enabled, and set it to false.
  • Brave Browser: Brave has built-in protection. Go to Settings > Privacy > WebRTC IP Handling Policy and select "Disable non-proxied UDP."
  • Chrome/Edge: These browsers don't have a simple off-switch. You should install the uBlock Origin extension and enable WebRTC leak prevention in its settings.

Why is My Local IP Exposed?

WebRTC also reveals your Internal (Local) IP (like 192.168.1.1). While this doesn't reveal your physical location, it helps trackers identify you uniquely. Modern browsers like Chrome now use mDNS to hide these local IPs behind a random .local address.

Frequently Asked Questions

Does a VPN always stop WebRTC leaks?
No. Most VPNs only encrypt your data traffic. They do not block the browser's internal requests for local IP discovery. Always test your VPN using this tool.

Is WebRTC dangerous?
It is not a virus, but it is a privacy risk. It was built for convenience, but its ability to bypass security layers makes it a tool for tracking.

Will disabling WebRTC break my browser?
It will disable browser-based video calls (like Google Meet or Discord Web). If you need those, use a dedicated app or re-enable WebRTC temporarily.
