First, 127.0.0.1 is a special case that always refers to the same host where the 
connection originates, so you can't really use that from another machine 
regardless of how you resolve the name.

That is up to your DNS server type.  If it is BIND/named you'll have a zone file 
for each domain it is serving with an 'A' record entry for a name and IP, and 
you would add CNAME entries for aliases or additional names.
