RFC 953                                                     October 1985
Hostname Server


   where  is a keyword indicating the nature of the
   response, and the rest of the response is interpreted in the context
   of the key.

   NOTE:  Care should be taken to interpret the nature of the reply
   (e.g, single record or multiple record), so that no confusion about
   the state of the reply results.  An "ALL" request will likely return
   several hundred or more records of all types, whereas "HNAME" or
   "HADDR" will usually return one HOST record.

COMMAND/RESPONSE KEYS

   The currently defined command keywords are listed below.  NOTE:
   Because the server and the features available will evolve with time,
   the HELP command should be used to obtain the most recent summary of
   implemented features, changes, or new commands.

      Keyword   Response

      HELP      This information.

      VERSION   "VERSION: " where  will be different for
                each version of the host table.

      HNAME 
                One or more matching host table entries.

      HADDR 
                One or more matching host table entries.

      ALL       The entire host table.

      ALL-OLD   The entire host table without domain style names.

      DOMAINS   The entire top-level domain table (domains only).

      ALL-DOM   Both the entire domain table and the host table.

      ALL-INGWAY

                format.

   Remember that the server accepts only a single command line and
   returns only a single response before closing the connection.  HNAME
   and HADDR are useful for looking up a specific host by name or
   address; VERSION can be used by automated processes to see whether a
   "new" version of the host table exists without having to transfer the
