multiple domains on 1 IP # - file layout

[Adam Smith]

Hello,
I am setting up a nameserver - multiple domains on 1 IP #. BIND 9.3.1 on 
FreeBSD 6.x;
I am not too clear on the exact format for these files in the master 
folder, could someone suggest the correct way. Special concerns as to 
whether all the domains should be listed here as under "Hosts" and 
"nickname". There is only one reverse_dns file used in the master folder 
and one db.* for each of the domains (zones) listed in the named.conf file.
Thanks!
