This could be further simplified by using inherited owner names -
that is, if a record's first field (the owner name) is left blank, it
inherits the owner name of the previous record. Also, there's no
reason to specify a class (IN in this case) anywhere in a zone file -
it inherits the class from the zone definition, and you're not
allowed to put multiple classes into a zone file. So the example
above can be simplified further like so:
$TTL 3600 ; 1 hour
@ SOA dssns.dss.state.la.us. rmccain.dss.state.la.us. (
2007091103 ; serial
1200 ; refresh (20 minutes)
600 ; retry (10 minutes)
1209600 ; expire (2 weeks)
3600 ; minimum (1 hour)
)
NS dssns.dss.state.la.us.
NS dssns2.dss.state.la.us.
A 205.172.49.49
MX 10 smtp-ext1.dss.state.la.us.
MX 20 smtp-ext2.dss.state.la.us.
acess A 205.172.49.23
acess-info A 205.172.49.23
acspoc A 205.172.49.9
