What is WebRTC Leak?

WebRTC is one of those fundamental technologies that enable you to perform peer-to-peer functionalities on your browsers. It is what allows you to perform video chatting, audio calling, and more.

Basically, the technology uses STUN (Session Transversal Utilities for NAT) protocol that ultimately relies on your public IP for making the peer-to-peer connection.


The STUN protocol, combined with a WebRTC vulnerability in some browsers, exposes your external (public) IP address to third-parties even if you are behind a VPN server.

Use our WebRTC Leak Test tool to find out whether your real IP is exposed or not.

How to Use the WebRTC Leak Checker?

As the name suggests, the tool is built to help users detect any potential IP leaks. Moreover, the tool is pretty easy to use.

You will notice two IP addresses when you use the tool: Public IP and Local IP.

Keep in mind that the public IP address is assigned by your ISP and the local IP is used on the local area network since the router assigns it. Anyway, it is the public IP address you should be worried about when using the WebRTC leak test tool.

Public IPs can be considered as your virtual identity on the Internet. It is the same IP that proves useful when it comes to extracting many sensitive details regarding the user. For instance, public IP can be used to track the exact location of the user.

Therefore, if the leak checker tool displays your actual public IP, even when you are using a VPN, it means that your real IP is being exposed.

5 Steps to Test WebRTC Leak (With and Without a VPN)

Various things could go wrong if any third-party such as a hacker gets their hand on your actual IP address. Therefore, it is advisable that you use a leak checker to ensure that your VPN is keeping your IP hidden from prying eyes.

Follow these simple steps to check your VPN for any potential WebRTC leak:

  • Disconnect and exit your VPN client
  • Go to What is my IP and check your IP address
  • Note down the displayed IP address and exit the webpage
  • Launch the VPN client and connect to any location
  • Now, use our WebRTC Leak Test tool to check the status

If the tool displays your public IP address, it means your VPN is leaking your IP. Likewise, if the tool doesn’t display any IP, it means your IP is hidden.

What is WebRTC & How Does It Work?

WebRTC is a real-time communication technology that allows users to communicate via their web browsers such as audio/video calling, etc. It uses a non-proprietary protocol that doesn’t require any additional plug-in or add-on to make the connection.

Moreover, there are many components that work behind the technology such as STUN/TURN servers, UDP/TCP, JSEP, signaling, etc. The technology uses these components to establish a connection between two browsers and, thus, allows seamless communication.
