WebRTC Leak Test

WebRTC is designed to establish a direct, high-speed connection between two browsers. To find the shortest path, WebRTC uses a protocol called ICE (Interactive Connectivity Establishment) to discover all your network adapters, including your local LAN IP and your real public WAN IP. Some browsers execute this discovery process outside of active VPN or proxy tunnels, resulting in a leak.

A Local IP (such as 192.168.1.X) is the internal address assigned to your device by your home router; it is not routing-capable on the global internet and poses minimal privacy risk. A Public IP is the unique address assigned to your modem by your ISP. If your real Public IP is exposed in a WebRTC scan, websites can easily track your exact location and identity.

You can block WebRTC leaks in a few ways: First, use a reputable VPN client with built-in WebRTC leak protection. Second, install specialized browser extensions (like "WebRTC Control" or "uBlock Origin" with WebRTC blocking enabled). Third, you can manually disable WebRTC in certain browsers like Firefox by changing "media.peerconnection.enabled" to "false" in the about:config settings.

Disabling WebRTC will not affect standard web browsing, streaming, or security. However, it will prevent web-based communication applications—like Google Meet, Discord, or Zoom running directly in a browser tab—from establishing voice and video calls. If you use these services inside your browser, you should use a VPN with WebRTC leak protection instead of disabling the feature entirely.

Standard IP lookup tools read your IP from the basic server request headers, which your VPN successfully changes. However, WebRTC uses JavaScript to query your browser’s internal routing tables. Because this JavaScript query runs locally on your machine, it can retrieve your actual hardware connection details and bypass basic proxy or VPN configurations.

Yes, both Brave and Safari have stricter default privacy configurations compared to standard Chrome. Brave includes native WebRTC handling settings (set to "Default Public and Private Interfaces" or "Disable Non-Proxied UDP") to mitigate leak risks. Safari restricts WebRTC from sharing your local IP addresses unless you explicitly grant camera or microphone permissions to a website.
