The internet addressing scheme proposes addresses looking like
	domain-specific-string @ domain

The standard permits domains to have subdomains separated by dots,
which permits domain names like
	hou3c.att.uucp

This means that hou3c is a subdomain of att, which is a subdomain
of uucp.  This is a nice naming scheme except that 1) the only
official domain is "arpa", and 2) many machines don't understand
it anyway.  Ucbvax does understand it, and it accepts bitnet as a
domain, so you can send mail to machines on the BITNET by mailing
to "...!ucbvax!user@machine.bitnet".
