WebRTC Leak Test
Detect local and public IPs exposed via WebRTC.
WebRTC Leak Test gathers ICE candidate addresses using a STUN server. Private or unexpected public IPs can indicate a VPN leak. Run the test while connected to your VPN to verify.
Frequently Asked Questions
What does a leak mean?
If you use a VPN but see your real public IP in ICE candidates, WebRTC may be bypassing the VPN tunnel.
Is STUN traffic private?
A STUN request reveals your network path to the STUN server. We use Google’s public STUN endpoint.
No IPs found?
WebRTC may be disabled, blocked by an extension, or unsupported in the browser.
