TTL The time-to-live of the RR. This field is a 32-bit integer in
units of seconds, and is primarily used by resolvers when
they cache RRs. The TTL describes how long a RR can be
cached before it should be discarded.
A host address.
PTR A pointer to another part of the domain name space.
CNAME Identifies the canonical name of an alias.
MX Identifies a mail exchange for the domain.
SOA The last field in the SOA is the negative caching TTL. This controls how
long other servers will cache no-such-domain (NXDOMAIN) responses
from you.
The maximum time for negative caching is 3 hours (3h).
$TTL The $TTL directive at the top of the zone file (before the SOA) gives a
default TTL for every RR without a specific TTL set.
