DNS leak test
A real DNS leak test needs a logging DNS backend. A browser page alone cannot reliably tell you which resolver handled your DNS queries.
Current status
Full resolver-based DNS leak test is not enabled yet
To do this properly, iptest.pro needs its own authoritative DNS infrastructure or resolver logging flow tied to unique test tokens.
What a real DNS leak test needs
The site must generate unique hostnames and observe which DNS resolvers query them.
That means DNS requests need to hit infrastructure controlled by the test service, not just the web server.
Once that backend exists, the page can compare resolver origin, country, network and consistency with your visible public IP.
