Well, your DNS needs to be authoritative for both forward and reverse.
If you are trying to do this for less then a /24 block the zone files
get messy quick because of the 8bit boundaries. You seem to be trying
to do this for a /16. I'll bet you're missing the named.conf entries
and related reverse zone files:
Odds are you'll want to have zones:
zone "1.30.172.in.addr.arpa" {
type master;
file "master/1.30.172.in.addr.arpa
notify yes;
}
....
zone "255.30.172.in.addr.arpa" {
;; or slave config since you'll have more than 1 ns
type slave;
file "slave/255.30.172.in.addr.arpa";
masters { x.y.z.a; };
}
Or some larger splits of that.
You're going to have give me a netmask for more help.
$ORIGIN .
$TTL 3600 ; 1 hour
0.28.172.in-addr.arpa IN SOA ns1.rws. admin.Z. (

$ORIGIN 0.28.172.in-addr.arpa.
