DNS Leak Test

Hello

Looking up your connection…

Standard is quick. Extended runs more rounds to catch load-balanced resolvers.

WebRTC leak not run

WebRTC can reveal your real IP even behind a VPN, straight from the browser.

Local IPs
Public IPs

Location consistency not run

Mismatches between your IP's country, your timezone and your browser language are classic de-anonymisers.

What is a DNS leak?

Every website you visit starts with a DNS lookup that turns a name like example.com into an IP address. Whoever runs the DNS resolver that answers those lookups can see the name of every site you connect to. If you use a VPN but your lookups still go to your ISP's resolver — or any resolver outside the tunnel — that's a DNS leak: your VPN hides your traffic, but not the list of places you go.

This test gives your browser a set of one-time hostnames to resolve. Because they're unique, the resolver you're actually using has to ask our name server directly — which lets us show you exactly which DNS servers see your activity, and give you a straight pass or leak answer instead of a table to decode.
