Hi Chris,
I run a number of internal clients on 10 address space. what i did was break up
each Zone into Class B's 10.1.x.x , 10.2.x.x then my forward and reverse files
into class C's. Each record 10.1.1.x . 10.1.2.x, 10.1.3.x, . then scale ass
needed. providing the means to add forward and reverse to any address within
that address space.
here is a sample, note the sub folders for sanity sake.
############## my LAB ####
############## 10.153 #####
zone "1.153.10.in-addr.arpa" IN {
file "/var/named/in-arpa-10/153/in-arpa.my-lab1.db";
type master;
};

type master;
