DoT Server
Verification: Take the world's top DoT servers. Use openssl to connect on port 853 and record results. Compare.
DoH Server
Verification: Take the world's top DoH servers. Use "testssl.sh". Compare.
SSH Server
Verification: Take any SSH server of your choice. Use "ssh-audit". Compare.
DNS Resolver
Verification: You cannot - my DNS Resolver is not exposed to the internet. That would create unnecessary DOS Attack risk with amplification. Suggest use DoH and DoT for DNSSEC verification. Compare with your local resolver.
