WebRTC Leak Test

Check if your real IP address is leaking through WebRTC connections.

WebRTC Leak Test

Check if your real IP address is leaking through WebRTC connections.


What is a WebRTC Leak?

A WebRTC leak occurs when your real IP address is exposed through WebRTC connections, even when you're using a VPN or other privacy tools. This happens because WebRTC can bypass your VPN tunnel and access your local network interfaces directly.

Why WebRTC Leaks Matter



  • Your real location can be revealed

  • Your VPN usage can be detected

  • Your privacy can be compromised

  • Your anonymity can be broken

How to Prevent WebRTC Leaks




  1. Browser Settings:

    • Firefox: Set media.peerconnection.enabled to false

    • Chrome: Install the WebRTC Leak Prevent extension

    • Safari: WebRTC is disabled by default




  2. VPN Settings:

    • Enable "Block WebRTC" in your VPN client

    • Use a VPN that supports WebRTC leak protection




  3. Network Configuration:

    • Configure your firewall to block WebRTC traffic

    • Use a router that supports WebRTC blocking




Note



This test is performed entirely in your browser. No data is sent to our servers.
The test uses Google's public STUN server to gather ICE candidates.




Frequently Asked Questions





What is a WebRTC leak?


A WebRTC leak occurs when your real IP address is exposed through WebRTC connections,
even when you're using a VPN or other privacy tools. This happens because WebRTC can
bypass your VPN tunnel and access your local network interfaces directly.




How accurate is this WebRTC leak test?


This test is highly accurate and uses the same methods that websites use to detect your IP address.
It creates a real WebRTC peer connection and analyzes the ICE candidates to identify potential leaks.
However, results may vary depending on your browser settings and network configuration.




What should I do if a WebRTC leak is detected?


If a WebRTC leak is detected, you should:



  • Install a WebRTC blocking browser extension

  • Disable WebRTC in your browser settings

  • Use a VPN with WebRTC leak protection

  • Configure your firewall to block WebRTC traffic




Does this test work on all browsers?


This test works on all modern browsers that support WebRTC, including Chrome, Firefox, Safari, and Edge.
However, Safari has WebRTC disabled by default, so you may not see any leaks on Safari.




Is my data safe when using this test?


Yes, your data is completely safe. This test runs entirely in your browser and doesn't send any
information to our servers. The test only uses Google's public STUN server to gather ICE candidates,
which is the same process that websites use for WebRTC connections.




How it Works

This tool uses the WebRTC API to detect potential IP address leaks. It creates a peer connection and checks for any local or public IP addresses that might be exposed through WebRTC's ICE (Interactive Connectivity Establishment) process.

Technical Details

The test works by creating a WebRTC peer connection, gathering ICE candidates, analyzing the candidates for IP addresses, comparing found IPs with your public IP, and detecting potential leaks.

  • Uses the WebRTC RTCPeerConnection API
  • Implements ICE candidate gathering
  • Analyzes STUN/TURN server responses
  • Detects both IPv4 and IPv6 leaks
  • Works in all modern browsers

About This Tool

This tool is designed to help you understand your system's configuration and identify potential privacy and security issues.

All analysis is performed locally in your browser - no passwords, personal data, or system information is sent to our servers.

Use this tool to assess your privacy status, check for potential leaks, and understand how your system appears to websites.
