                      MORE ON STANDARD HOST NAMES
	
   The Network Information Center is a logical place to handle this
   problem of Standard Host Names and so the ball now rests here.
   This is clearly a delicate subject with people having strong
   feelings and attachments to names.  No past proposal, including
   RFC 247, NIC 7668, has yet achieved any acceptance.  This
   identification seems a natural thing and should be taken into
   account in setting up a naming scheme.  Therefore, the following
   proposal is offered which I hope may be satisfactory to everyone.

   Any naming scheme must:

      (1)  Recognize the expanding character of the Network, with
      the potential eventually of several hundred sites.

      (2)  Recognize the need for abbreviations to simplify typing.

      (3) Recognize the use of names on hardcopy and online
      documentation

      (4)  Recognize people's strong identification with historical
      names associated with their project.

   To meet these needs, we propose adoption of a hybrid scheme
   related to those in the other past proposals.

   Each host will have a formal name of the form:

      <Institution Mnemonic>    "-"   <Host or NIC Station Mnemonic>

      and an optional nickname of the form:

                  <Nickname>

   We have heard no arguments to support severe restrictions on name
   length and, therefore, human considerations should probably
   prevail, but would suggest the following guidelines.

      <Institution Mnemonic> will be at most 4 characters, formed as
      per RFC 247, NIC (7688,).

         Examples of Institutions being:  AMES, CASE, BBN, UCLA,
         SRI, MIT, HARV, MITR, etc.

         We must recognize that in the future there may be multiple
         IMPS and TIPS and combinations at a given institution, so
         that there is not a one-to-one correspondence between
         <Institution Mnemonic> and IMPS or TIPS.  Also affiliated
         with the Network, there will be groups and individuals
         without an IMP or a TIP, or with just a terminal to a TIP,
         whose organizations need unique names.

      <Host or Nic Station Mnemonic> will not have any restriction
      on length, but should if possible be short.  In picking <Host
      or NIC Station Mnemonic>, an order of priority for choosing
      this mnemonic might be

         (1)  Suborganization within the <Institution Mnemonic>.

         (2)  Project mnemonic.

         (3)  Machine designation.

         (4) The suggestion in RFC 247, NIC 7688 to include the
         designation TIP or TEST should probably be followed as
         conveying useful information.

         Examples might be:

            ARC, NMC, NCCTIP, TENEXA, TENEXB, MULTICS, ILLIAC, SAIL,
            DMCG, IMP, TX2, etc.

      The <nickname> should be unique within the network community,
      short, and preferably should be the same as <Host or NIC
      Station Mnemonic> to make life easy for people having to learn
      them.

   I would strongly recommend that Telnets recognize both the Formal
   Name and the Nickname.

   Now the sticky question:  who chooses the names?  The only
   satisfactory answer is to allow the hosts, through their liaison,
   to choose their own names, possibly subject to some discussion if
   duplicate or extra long names are picked.  Hosts or stations at a
   given institution should use the same <Institution Mnemonic>.

   Let's settle this issue as soon as possible, say by November 5;
   each liaison please send me your names by then.

   If there are any implementation hardship cases, other than TIPs,
   caused by the above scheme, please let me know as soon as
   possible.
