What you are looking at
Answers come from public recursive resolvers, so this is what an ordinary client on the internet sees, cache included. The TTL column counts down: it is the number of seconds this answer may still be reused before a resolver asks again.
Names starting with an underscore are not hostnames; they carry policy. _dmarc holds your DMARC policy, _mta-sts and _smtp._tls the transport security ones, and selector._domainkey the public half of a DKIM signing key.
