📝 What Is a WebRTC IP Leak

A term VPN users and privacy-conscious people often hear is a WebRTC IP leak. This article explains what WebRTC is, how a leak happens, and how to check your own connection.

What is WebRTC?

WebRTC (Web Real-Time Communication) is a web standard that enables voice and video calls and real-time data transfer without needing a separate plugin. Many video call sites rely on it.

How does an IP leak happen?

To establish the most efficient connection, WebRTC gathers information about your device network interfaces. In some cases, this process can expose your real local network address to the site you are visiting, even behind a VPN. This is called a “WebRTC leak.”

Why does this matter?

If your reason for using a VPN is to hide your real location or identity, a WebRTC leak can partly undermine that protection. A leak by itself is not automatically dangerous, but it may not match your privacy expectations.

How do you test your own connection?

Our Browser Security Check checks, in real time, whether your browser exposes a local IP address through WebRTC and shows the result clearly. Many modern browsers use a mechanism (mDNS) that masks the local IP to reduce this risk, and your result reflects that too.

Conclusion

A WebRTC leak is not a major risk for most people in daily use, but it is worth checking if you care about privacy or use a VPN. You can see your own status in a few seconds.
