What an IP leak is
Even with a VPN, a site can learn your real IP via WebRTC or DNS queries that bypass the tunnel.
Why check DNS
If DNS goes through your ISP, it can see which sites you open even with the VPN active.
Test privacy
IP and geo come from our own edge (not third parties); WebRTC runs in your browser. We keep no logs.
