WebRTC Leak Test

A VPN is often used to hide your IP address in order to surf the Internet anonymously. However, should you have incorrectly configured your VPN software, your original IP address or other sensitive information can be leaked. The EXPERTE.com WebRTC Leak Test checks whether your private IP address is still public as the result of a WebRTC leak.

Note: For the test to produce meaningful results, you must be connected to a VPN.

WebRTC is a protocol that allows two computers to communicate with one another, enabling things such as browser-based video conferences or data transmissions.

To establish a connection with another computer, information about the IP addresses must be exchanged. In some browsers, the user's local and public IP can be read via JavaScript. Websites prepared to capture this information are thereby able to find out your original IP address, even when you connect to them using a VPN.

Through a WebRTC leak, a website operator discovers your private IP address. Should you use a VPN to preserve your anonymity online, these kinds of leaks severely undermine the protection a VPN is supposed to provide.

The easiest way to prevent a WebRTC leak is to disable WebRTC in your browser. You can do this either by changing your browser's settings or with a browser extension.
