What Is a VPN Leak?
A VPN leak occurs when your real IP address or DNS queries are exposed despite being connected to a VPN. This can happen through DNS leaks (your DNS queries bypass the VPN tunnel), WebRTC leaks (your browser reveals your real IP through peer-to-peer connections), or IPv6 leaks (your IPv6 address isn't routed through the VPN). Our test checks for all three types to ensure your VPN is protecting your privacy.
