What is WebRTC?

Let’s start with introduction of WebRTC. As we explained earlier, WebRTC or Web Real-time Communication (WebRTC) is an open-source technology which allow the browsers to communicate without requiring a dedicated server. 

Now when it comes to communication, both web browsers need to know their IP Addresses. Normally, it won’t be a problem because you will be using your own IP Address online for browsing, shopping and other stuff. However, if you are using VPN to hide your identity, it’s very important that your browser shouldn’t share your original IP Address with any other browser. If your browser does so, it’s WebRTC Leak and third-party websites can use your IP Address to track your online activities and know your identity.
