WebRTC Leak Test
Browsers can reveal your real IP through WebRTC, even behind a VPN. Run the check to see what is exposed.
About WebRTC Leak Test
A WebRTC leak test checks whether your browser exposes an IP address that differs from the one websites normally see. It is most useful if you use a VPN or proxy, because a leak means your real IP address is visible despite the tunnel. The test asks a public STUN server for your IP the same way a video-call site would, and compares the answer with your connection.
Frequently asked questions
What is a WebRTC leak?
WebRTC lets browsers connect directly for video calls and file sharing, and to do that it asks a STUN server for your public IP. Some browsers return your real IP this way even when a VPN is active, which exposes your true location.
How do I fix a WebRTC leak?
Use a VPN that blocks WebRTC leaks, turn off WebRTC in your browser (Firefox lets you set media.peerconnection.enabled to false), or install a reputable extension that restricts WebRTC. Then run this test again to confirm the leak is gone.
