What is WebRTC and how to disable it?

Quick transition to setting up browsers

WebRTC (from Web real-time communications) is a technology that allows you to transfer audio and video streaming data between browsers and mobile applications.

The development of this technology is competing with Skype. WebRTC can be used to organize video conferences directly in the browser. The project has open source code and is actively promoted by Google and in particular the development team of Google Chrome browser.


How WebRTC works

Browsers of users thanks to WebRTC technology can transmit data directly to each other. WebRTC does not need a separate server that would store and process the data. All data is processed directly by browsers and mobile applications of users.

How WebRTC works


WebRTC technology is supported by all popular browsers Mozilla Firefox, Opera, Google Chrome (and all browsers based on Google Chrome), as well as mobile applications based on Android and iOS.


The Danger of WebRTC

The danger of WebRTC technology is to determine your real IP address. Since the connection goes directly to another user, browser, website or mobile application, the network settings are ignored. To create audio and video communication, browsers must exchange external and local IP addresses.

Anonymous VPN service solves this problem and hides the real IP address. The maximum that can be detected is the local IP address assigned to the user by the VPN network. This is not dangerous, since the same local IP addresses will be shown if you use a router to distribute the Internet.

WebRTC does not determine the real IP address when using VPN


If you use a proxy, then WebRTC will be able to determine your real IP address for the proxy or IP address of the VPN server if you use the VPN + proxy chain.

WebRTC also determines your real IP address using Tor network.

The best solution is to disable WebRTC technology if you do not use it.
