<div dir="ltr"><br><div>You're right, one of the many whoami records would work too, but I usually avoid those for two reasons; 1. users mostly don't know how to make DNS queries and often copy the wrong IP address back in their reports, and 2) the response is cacheable and so unreliable when your resolver has multiple IPs, or if you're testing several resolvers from behind a caching stub resolver. So I wrote the HTTP/Javscript interface with a cache buster to get rid of the problem.</div>
