How does one configure a machine to have more than one IP address?

I read this on the hosting company's page I mentioned earlier. They said
this affected Netscape 1.1 and lower...

mod_rewrite might be able to handle this task. In fact, mod_rewrite can
even be used to set up virtual hosts without using an apache Virtual Host
directive!

Perhaps I could do something like this:

Configure a virtual host in Apache as bar.com to be my AOLserver, then
create a rewrite rule with mod_rewrite that sends the request to AOLserver
if the host matches bar.com...

something a bit like...

RewriteRule ^(bar\.com) $1:81

This sounds promising too...

My hacker mind loves this puzzle! It's so convoluted and...down right
subversive! Who'd want to run two webservers on one machine ANYWAY?!
MUhahahahah!
