[vox-tech] Setting up DNS with BIND

[Nicole TWN]

Hi gang

I could use some help filling in the gaps in my knowlege of DNS servers; 
time spent on Google has only confused me.  Here's my understanding of how 
BIND works:
1. Looks in /etc/named.conf to find out whether it's a master or a slave, 
and, if it's a master, where its zone file is;
2. Looks at its zone file, where it finds a bunch of 'A' or 'PTR' records 
like "192.168.1.42    A     one.example.com."  This is also called the 
'forward' DNS file.

Now, where does the reverse DNS file fit in?  I've come across references 
to such a thing--apparently they're full of records like 
"42.1.168.192.in-addr.arpa.  A   one.example.com"  I think I'm supposed to 
add a corresponding reverse record whenever I add a forward record (and 
before rehupping named), but what's the reverse file usually called and 
where does it live?

Thanks--
