DNS resolvers

The standard test takes about 5 seconds and uses 4 sources. The full test takes about 15 seconds and repeats each source.

How to read the result

If the resolvers are in the same country as your IP, DNS is usually going through your proxy. If you're on a proxy but see your local ISP or a local public DNS, your DNS isn't proxied, and both websites and your ISP can see which domains you visit.

A resolver in another region isn't always a leak: many proxy apps hand DNS to public resolvers like Google or Cloudflare, whose servers may be in a neighboring country. Check against your proxy app's DNS settings.
