Your ferocity probably frightened the Google elves. ;)

This is an httpd (Apache?) configuration issue. "VirtualHost", 
"NameVirtualHost" and other directives. Don't Google -- let the poor 
elves regain their wits -- you have all the documentation with your 
Apache install.

You want a wildcard "A" or "CNAME".

; assuming $ORIGIN and $TTL properly defined
*		A	your.ip.add.ress
; or CNAME:
*		CNAME	your.resolvable.hostname.example.com.
; leave off ".example.com." if it's under your $ORIGIN

DNS points the browser to an IP address ... that is all. Your HTTP 
daemon has to do the rest of it.
