delegated reverse dns for very small zone

[Ken A]

Hello,

A bit of a DNS rookie here & I've not run accross this before using bind.

Pacbell has delegated the reverse dns to us for 66.127.104.201-206.

I need to create a PTR record for mail.ncoinc.org on 66.127.104.202

According to
http://www.dnsstuff.com/tools/traversal.ch?domain=202.104.127.66.in-addr.arpa&type=PTR
ns1.pbi.net says to look to 202.104.127.66.in-addr.ncoinc.org for the 
answer.

We are authoritative for the ncoinc.org domain, but I'm not sure how to 
add this PTR record to the zone. Should I create a separate reverse file 
like I would for a full /24 network, or can I combine it in the forward 
zone file?
What should the entry in named.conf look like? Should it this:

zone "104.127.66.in-addr.ncoinc.org" {type master; file "ncoinc.org"; };

? I'm sure I'm missing some syntax I've not used before.
Thanks for any help.
