   The enclosed is what we hope will be accepted as a list of
   official formal host names and nicknames.  As no other subject
   worked on by the NWG has generated so much comment, it is
   worthwhile to review briefly how this list came into being.

   The need for some standard set of names recognized by NCP's and
   Telnets and usable on hardcopy to designate a persons affiliation
   had been recognized for some time and several sets of names were
   in use.

   Peggy Karp issued the first formal proposal of a set of standard
   names in RFC 226, NIC 7625.  This proposal was answered by a
   number of counter proposals and culminated in RFC 247, NIC 7688.
   People still were not happy with this proposal as names normally
   associated with hosts or projects were not used.

   At the last NWG meeting a number of people discussed the name
   problem and agreed that the only reasonable compromise solution
   was to have both formal names and nicknames and to let the people
   at the hosts choose their own names within the guideline which the
   previous dialog had seemed to agree on.

   The guidelines were summarized in RFC 273, NIC 7837 and the NIC
   agreed to collect and publish the names that the people at each
   host indicated they desired.  A number of names were received and
   a tentative list was published as RFC 280, NIC 8060.  More people
   responded with their desired names or changed the ones in the
   above list.

   Almost all sites have since responded and the following list
   resulted.

   I think people should feel free to change their host name when
   ever the situation warrants.

PROBLEMThe ARPANET had no standard way to refer to hosts across different systems. Different sites used different names, making it hard for NCP implementations and Telnet users to specify which computer they wanted.
MECHANISMAfter a long debate, the NIC collected suggestions from each site and let them choose formal names and nicknames within agreed guidelines, creating a unified registry.
REPLACED WITH EXPANDED LISTRFC 289 presents the negotiated list mapping formal names, nicknames, and network addresses for all ARPANET hosts as of December 1971, but was replaced by RFC 384 as the network grew.

§1The Naming Debate

Richard Watson at SRI explains the history of host naming on the ARPANET. The need for standard names had been recognized for years: NCPs (Network Control Programs) and Telnet users needed a consistent way to refer to hosts. Multiple competing name schemes had emerged, causing confusion.

Peggy Karp proposed the first formal standard (RFC 226), followed by counter-proposals and RFC 247. These attempts failed because they did not use names naturally associated with the hosts themselves.

Different places called their computers by different names, so the network couldn't be sure which computer you meant. People couldn't agree on what to call them.

§2The Solution

At an NWG meeting, the consensus emerged that the only workable solution was to support both formal names and nicknames. Guidelines were established (RFC 273), and the NIC invited each site to choose their own formal name and preferred nickname within these guidelines.

The NIC collected the responses, published a tentative list (RFC 280), and refined it as more sites responded. By December 1971, almost all sites had provided their preferred names.

They decided each site could pick both a fancy name and a short nickname. Everyone sent in their choices, and this list is the result.

§3The Official Registry

RFC 289 lists all ARPANET hosts with three pieces of information for each: the formal name (such as UCLA-NMC or MIT-MULTICS), an optional nickname (such as CCN or MIT-M), and the decimal network address (1 through 158 in this period).

The list covers early ARPANET sites including UCLA, Stanford Research Institute, UCSB, Utah, BBN, MIT, RAND, Stanford, Harvard, Lincoln Lab, and many others. Sites were encouraged to change their names in future if the situation warranted.

The list shows each computer's formal name, its short nickname, and its number on the network. Sites that wanted to rename themselves later could do so.
