               The Nic's View of Standard Host Names

 The NIC strongly favors standardization of host names. People will
 get used to the names appearing on documents coming from or through
 the NIC and so we would like the ones used by NIC and the ones used
 in Telnets to agree.  In the absence of agreed standard names, we
 have chosen some.  We are not particularly partial to the ones we are
 using, but do feel any standard naming scheme take into account most
 of the following considerations.

    (1)  Names consist of two parts, SITE and HOST, preferably
    separated by a delimiter such as a dash.

    (2)  Site and Host names have some mnemonic value, if possible not
    involving the name of the computer as computers will change, but
    the organization running it will remain.

    (3)  We strongly recommend at least 8 characters be allowed,
    including one delimiter.  The NIC now uses 12 characters maximum.

    (4)  Assuming 8 character names, we recommend that the site name
    be a maximum of 6 characters and that Host names at a given site
    be unique in the first six characters.  Thus, with the delimiter,
    sites desiring to only have 4 characters in their tables can
    accept all characters typed by the user and truncate to 6
    characters and still achieve uniqueness.

    (5)  Once the NWG has set a standard syntax and names for present
    Hosts, the NIC should be responsible for maintaining the standard
    and assigning names to new hosts and other groups involved in
    Network dialogue. Besides hosts there are NIC stations and
    individuals in organizations not on the Net involved in the
    Network dialogue.  The NIC needs to assign names to these Network
    affiliations and will use the rules set by the NWG.
