Reveals which DNS servers are actually resolving your queries right now.
One button runs a standard or extended test and lists every resolver that answered, with its owner and country. It exists to catch the common VPN failure where traffic goes through the tunnel but DNS lookups quietly leak to your ISP, handing them the list of every site you visit. If the results name your ISP while a VPN is connected, the VPN is not doing what you think.
Questions
Works the moment the page loads. No account, no email, no trial. It tests DNS only — WebRTC, IPv6 and traffic leaks need separate checks.
Yes. DNS Leak Test sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
