Okay. What about domain-style addresses that look like ARPA addresses but may never touch the Arpanet? Is there a problem? Because, for example, user@decwrl.DEC.COM would go via the ARPANET from an ARPANET host, but would go via DEC's internal network from decuac. And even though we are not an ARPANET host, avolio@decuac.DEC.COM will get to me. And it may go via UUCP or ARPA or any number of other ways. And user@host.ATT.COM won't touch the arpanet from here as neither will user@host.UMD.EDU. What I am getting at is, with the implementation of domains across networks, including optional usage on the 'UUCP network,' the transport mechanism will not be indicated, so those IBM business cards could say "user@ibm.com" and, unless one knew the communication channels, no one should object to the use. Because, user@host.SUB2.SUB1.TOPDOMAIN may or may not cross the DDN network. -- Fred @ DEC Ultrix Applications Center UUCP: {decvax,seismo,cbosgd}!decuac!avolio INET: avolio@decuac.DEC.COM
