do i edit and add an entry to virtual hosts in the httpd.conf file... ?
no, you add matching forward and reverse dns records for the ip you're using on the appropriate nameservers. (go read RFC 1035 - Domain names - implementation and specification)
just edit your /etc/hosts and add your fake domain and point it to 127.0.0.0 for localhost then run the eggy on 127.0.0.1 and it will show *!*@whatever.com
A good book, several's MB's of FAQ's, a few spare weeks, a lot cool, calm meditation and at least the knowledge to be able to setup a IP network, using linux without a wizard.
Some pointers.
If you are only using a modem, forget it, it's not worth the hastle.
If you are signed up, and using a everyday cable/DSL provider, forget it, they will not be prepered to assign static IP's to your system, and allow RDNS (reverse DNS) control of them.
To be able to setup a V-host, you need at least 1 static IP, a domain name or sub domain name, which your computer can answer for in a DNS query, a DNS server (BIND) to answer those queries, and your ISP has to setup there systems, to forward DNS queries on the static IP.
If you do not understand the aim (not the ability to set it up, just what they acheive), then youy are well over a month away from puttin any of this into action.

This is not necessarily true for DSL. If you live in europe, there are plenty of dsl isps that will do this (mine does, and I can think of at least 4 others in england alone - and all of them will assign as many IPs as needed as long as you can justify their use under standard RIPE rules)
wrong. bt has nothing to do with the routing - its fully isp based. all bt do is provide the atm interface, and present the dsl to the correct auth server for the isp. once thats done, the auth server itself defines the routing. if it wasn't for it being a dumbass idea, there's nothing stopping them routing a /8 to you if they felt like it.
Have to agree with Peterson on this one, the IP ranges are registered to the ISP's who then control the Reverse DNS for those. BT's involvement is simply providing the ADSL link over their ATM network.
However most Uk ISP's wont happily give you a fixed IP without an extra fee, some wont at all, because they use an overbooking ratio on the IP ranges they have, meaning that in theory not all of them are in use at the same time so they dont have to own enough IP's for all their customers, just enough for the average no of users on at any one time.
There are one or two ISP's in the UK who are giving out multiple fixed IP's for a fee at the moment providing you can give valid reasons for wanting them.
