What Is a DNS Leak?

A DNS leak occurs when your DNS queries go through your ISP's servers instead of through your VPN tunnel. This means your ISP can see which websites you visit, even when connected to a VPN. This tool checks which DNS resolvers are being used to help you identify potential leaks.

What Is a WebRTC Leak?

WebRTC (Web Real-Time Communication) is a browser technology used for video and voice calls. It can sometimes expose your real IP address even when using a VPN, because it uses STUN servers to discover your public IP. This tool checks if your browser is leaking your real IP through WebRTC.
