hitechcreations.com has always been theirs, ever since day 1 when I discovered the game. They also use flyaceshigh.com because it's easy to remember (marketing).
Anything before "hitechcreations.com" is a subdomain, not a separate url really, as a different part of the same page. beta.hitechcreations.com and bbs.hitechcreations and
www.hitechcreations are all on the same domain.
It's common to buy multiple urls for a company. Some even go so far as to buy up slanderous or negative sounding urls to prevent folks from putting up websites that trash them (like, AOLsucks.com just as an example).
