DNS Leak Test
This page triggers lookups for unique hostnames and then checks which DNS resolvers reached the authoritative zone. It is designed to show whether your DNS requests appear to come from your VPN, your ISP, or a public DNS provider.

Observed DNS Resolvers
How to read the result
- If you are not using a VPN, your ISP resolver can be normal.
- If you are using a VPN, you usually want to see the VPN provider or an intentional privacy DNS provider.
- This test is strongest when you compare the resolver list before and after enabling your VPN.
This test generates random probe hostnames and waits for DNS query logs.
