DNS Leak Test

DNS stands for Domain Name System, and in a nutshell, the internet service provider who runs your DNS server can log and track every website and app you use. Even if you use tools like VPN, your DNS queries may still be visible to your ISP for different reasons. A DNS leak test checks exactly that by sending several domain names for the VPN to resolve, and if one of the servers in the results belongs to your ISP, the VPN likely has a DNS leak.

DNSleaktest.com offers a simple test to determine if your DNS requests are being leaked, representing a critical privacy threat.
