[net.mail] Internet addresses

stern@bnl.UUCP (Eric Stern) (12/23/83)

   Is there a consistent method of specifying addresses of
people and machines on a network other than that of the sender?
I've heard that you need a name, host, and domain. Can someone
define these?  In particular how would I specify an ARPANET
address from UUCP and vice-versa?  How about BITNET?
                                       Thanks in advance,

                                            Eric Stern

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".
