There is no requirement to have a website on  blah.com, as there is also
no requirement to have one on www.blah.com
It's just been the more expected way, you could put your website on
foobar.blah.com for all the Web/DNS cares, but not many people will
likely find it

irrelevant, you call it whatever you want, mostly this is used in some
hosting companies so they don't need to think up silly custom names.
With so much phishing around these days, what would you trust
www1.netbank,   www2.netbank? or ...  hotpies.netbank,
fishnchips.netbank  


(Oh I hope mailscanner doesnt think i'm impersonating netbank now and tag this message as suspected fraud :))
