Test for WebRTC, DNS, and IPv6 leaks that can bypass VPN encryption. A passing result means your real IP and DNS queries are not visible to websites while the VPN is connected.
WebRTC leaks expose local and public IPs through the browser. DNS leaks send queries to your ISP resolver instead of the VPN. IPv6 leaks route traffic outside the tunnel when IPv6 is enabled but not tunneled.
Connect your VPN, open each test below, and confirm no result shows your real ISP IP or DNS server. Disconnect VPN and re-test to see the difference.
A VPN leak is any path where traffic or metadata exits outside the encrypted VPN tunnel, revealing your real IP or DNS queries.
Disabling WebRTC in the browser prevents STUN-based IP leaks. Many privacy-focused browsers block WebRTC by default.
