DNS Redirect, Alias, 301, CNAME and Football

I'm convinced, after reading Cre8asiteforums' Multiple Domain Names & IIS?, Just set it in IIS or 301 Re-Direct ..., that programmers are not unlike football players. They like to call out code words to their team mates and spend hours practicing plays to fake out the offense. Okay. I take that back. Programmers AND SEO/M's are like football players.

"An ANAME points a domain name to an IP, i.e.: blah.com => xxx.xxx.xxx.xxx

A CNAME points a domain name to another domain name, i.e.: blah.com => webserver.blah.com"

What I tell ya?
