This question borders on answering something that has been plaguing me for 
some time. I have just upgraded to 8.2.2P5 from 8.1.2. While I thought I 
had a pretty good handle on reverse setups for partial class C's, I no 
longer believe I do. I've checked the FAQ's that came with 8.2.2P5 (hoping 
this is the FAQ everyone is referring to, but quite possibly, I am wrong in 
that assumption, but these docs seem to focus a lot on 4.x BIND).

At any rate, I have 32 addresses assigned to me, and I want to do the 
reverse for these (the ISP has said they will delegate). What I would like 
to know is:

a) the approved construction in /etc/named.conf (what does that entry 
actually look like).

b) the approved construction of the zone file.

The actual 32 addresses start at 63.236.34.192 of which I am allowed to use 
196-222.

The reason I no longer think I'm doing this correctly (and thus, starting 
from scratch once again) is that I seem to be able to get dig to work but 
not nslookup, or vice versa, but never both, and I think some of my 
confusion is in the file naming (or maybe the named.conf construction), but 
I'm not sure why.

This is probably a horrible newbie question, and I apologize. If there is a 
FM for me to R, then please provide a pointer and I'll go read it before I 
bother the list again.

Thanks for your time.
