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
(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:
RWW 20 OCT 71 7837 More on Standard Names
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
I would strongly recommend that Telnets recognize both the Formal
Name and the Nickname.
