How to read the records
Hostname and TTL
The name identifies which label you are defining, and TTL controls how long resolvers may cache the answer.
MX records
Mail exchangers use a priority number. Lower numbers are preferred first.
TXT records
TXT records are widely used for SPF, ownership verification, DKIM helpers, and service policies.
