Default Another zone may be required

I believe you need another reverse DNS zone for the whole subnet,
In this zone, add NS records:
NS 1-30
NS 1-30
and a CNAM for each record you have control over, pointing to your 1- zone:
CNAME 1 1.1-30 (no trailingperiods, the full zone name is appended)
CNAME 2 2.1-30
CNAME 30 30.1-30

Therefore, given a lookup for, it will look for which returns 5.1-30 (no period, so really equal to which will then look in your 1- zone and find the PTR record for 5.

Note the 1-30 zone prefix is arbitrary and can be anything really, but it helps with identication.
