What Is an IP Leakage in WebRTC? The Invisible Hole

Introduction: The VPN's Blind Spot

You turn on your VPN, you see a new IP, and you feel safe. But then you visit a test site and... there it is. Your real, home IP address is visible. This is a WebRTC IP Leak. It is one of the most common ways that anonymity is 'broken' in modern web browsers like Chrome and Firefox.

How It Works

WebRTC is a tool that allows you to have video calls (like Zoom in a browser) without needing a separate app. To make the connection fast, WebRTC 'bypasses' your VPN and talks directly to your local network card, which can reveal your true IP to a malicious website.

Conclusion

A WebRTC leak is like a hole in the bottom of your submarine. It doesn't matter how expensive the sub is; the water is still getting in. Test for WebRTC leaks here.
