          Introduction In an era where online privacy is paramount, the intersection of WebRTC and proxy usage presents a critical challenge. WebRTC, or Web Real-Time Communication, is a powerful technology that enables peer-to-peer connections directly in web browsers. However, this capability can inadvertently expose your IP address, even while using a proxy.
