Depends on exactly what you mean by "DNS host". Do you mean 
*nameserver*? Chapter 4 of _DNS_and_BIND_ steps you through setting up a 
BIND nameserver. Or, by "DNS host" do you just mean adding the name of a 
host to DNS? Page 150 talks about adding A records.

Pages 76-78 of the _DNS_and_BIND_ book discuss hostname checking, and 
give a reference to RFC 952, which defines what is or is not legal for a 
hostname.

Page 63 of the _DNS_and_BIND_ book discusses multihomed hosts briefly, 
but basically yours is not even a DNS question. If you're asking "can I 
use secondary IPs of an interface?" that's an OS question. Seems rather 
obvious to me that if you can *configure* secondary IPs on an interface, 
that you'd be able to *use* them, but then, what do I know about 
whatever unnamed OS you happen to be running...?

Again, I refer you to page 150 of the _DNS_and_BIND_ book, which talks 
about adding records for hosts to zone files.

I'm having a little trouble parsing that question. Are you asking 
whether it's a good idea to run a nameserver on the same box as a 
webserver? The first part of chapter 8 of the _DNS_and_BIND_ book talks 
about some of the performance/availability/security issues you should 
consider in deciding where and how many nameservers you should run for 
your domain(s).

I think you need to actually crack the _DNS_and_BIND_ book again and 
read it more carefully this time...
