dns: detect DNS interception #1862

Open bassosimone opened 2 years ago

bassosimone commented 2 years ago

A user suggested to me this experiment to detect in-path DNS interception. Do the equivalent of dig $name @8.8.8.8 and check whether the returned IP address belongs to Google or not. It seems simple and powerful, we should try!

also it would be great to have +nsid too!
