l0pht, if you need a name for testing you can hardcode a name on your /etc/hosts file, if
you need the name being resolved on your lan, then you need to put it on your local DNS
For second question.. you need two names resolving to same IP, then you can tell to Apache to
chose what virtual host apply based on name used on request.. Take a look at name based Virtual hosts..
Here is some Apache docs telling about it... http://httpd.apache.org/docs/2.2/vhosts/name-based.html
