❓ Frequently asked questions

What is a WebRTC leak?▼
WebRTC can expose your real IP address — even when a VPN is active. Websites can exploit this to de-anonymize you.
Why is a server needed here?▼
To determine the public IP the browser queries a STUN server. That's exactly the mechanism a leak uses — otherwise the test would be worthless.
Is data transmitted?▼
Only the STUN connection needed to determine the IP. Nothing is uploaded or stored.
How do I protect myself?▼
Disable WebRTC in your browser (or restrict it via an extension) and use a VPN that blocks WebRTC leaks.
