[ih] Domain Names

[Vint Cerf]

no the bbn IMP (arpanet) specs stopped at IMP numbers and host numbers.

the NWG developed the notion of host names along with NCP, TELNET, FTP  
and SMTP

email addresses used the <local mailbox ID>@<official host name>  
convention adopted by Ray Tomlinson.

official host name meant: registered in the host.txt file at SRI NIC.
