            The DDN Network Information  Center  (NIC)  assists  Defense
            Data  Network  (DDN)  users  and  potential  subscribers  in
            obtaining pertinent information about the DDN and the Inter-
            net.

            The NIC supports several database and  information  servers,
            including  the  WHOIS registry of users, hosts, domains, and
            networks, the NIC/QUERY browsing  system,  and  the  TACNEWS
            server.   The  NIC  provides  host  name translation tables,
            maintains domain name system server files, assigns  IP  net-
            work  numbers  and autonomous system numbers, registers net-
            work users, and issues MILNET TAC access cards.  The NIC  is
            also  the  source of DDN documents and the complete Internet
            Request For Comments (RFC) series and index.

            The NIC maintains a toll-free hotline from 7 a.m. to 5  p.m.
            Pacific time at 1-800-235-3155.  Users experiencing problems
            with TAC login, or who have requests for NIC  services,  are
            encouraged to call.
