   6. It is the responsibility of the users of this host table to
   translate it into whatever format is needed for their purposes.

   7. Names and addresses for DoD hosts and gateways will be negotiated
   and registered with the DDN PMO, and subsequently with the NIC,

   before being used and before traffic is passed by a DoD host.  Names
   and addresses for domains and networks are to be registered with the
   DDN Network Information Center (HOSTMASTER@SRI-NIC.ARPA) or
   800-235-3155.

   The NIC will attempt to keep similar information for non-DoD networks
   and hosts, if this information is provided, and as long as it is
   needed, i.e., until intercommunicating network name servers are in
   place.

   ; (semicolon)   is used to denote the beginning of a comment.
                   Any text on a given line following a ';' is a
                   comment, and not part of the host table.

   NET             keyword introducing a network entry

   GATEWAY         keyword introducing a gateway entry

   HOST            keyword introducing a host entry

   DOMAIN          keyword introducing a domain entry

   :(colon)        is used as a field delimiter

   ::(2 colons)    indicates a null field

   ,(comma)        is used as a data element delimiter

   XXX/YYY         indicates protocol information of the type
                   TRANSPORT/SERVICE.

DOD INTERNET HOST TABLE SPECIFICATION


         "FOO"           transport known; services not known

         "BAR"           service is known, transport not known

         NOTE:  See "Assigned Numbers" for specific options and acronyms
         for machine types, operating systems, and protocol/services.

   Each host table entry is an ASCII text string comprised of 6 fields,
   where

      Field 1         KEYWORD indicating whether this entry pertains to
                      a NET, GATEWAY, HOST, or DOMAIN.  NET entries are
                      assigned and cannot have alternate addresses or
                      nicknames.  DOMAIN entries do not use fields 4, 5,
                      or 6.

      Field 2         Internet Address of Network, Gateway, or Host
                      followed by alternate addresses.  Addresses for a
                      Domain are those where a Domain Name Server exists
                      for that domain.

      Field 3         Official Name of Network, Gateway, Host, or Domain
                      (with optional nicknames, where permitted).

      Field 4         Machine Type
