Some extensions running within Chrome often need a feature known as WebRTC. It is a built-in feature that enables web applications and sites to stream audio or video content and exchange arbitrary data between browsers without requiring any intermediary. It makes it possible to share data and make audio/video calls without installing plug-ins or any other external software.
Unfortunately, WebRTC can reveal your original IP address even when the VPN is turned on; thus, it is known as a WebRTC leak. You will need an extension to prevent a WebRTC leak in Chrome. There are plenty of extensions available for the same purpose, but this google extension VPN is officially released by Google itself! The extension is not an IP changer on chrome but it enables the functionality of a Chrome extension.
