                    NIC.DDN.MIL HOST ADDRESS CHANGE
                 AND ROOT DOMAIN SERVER ADDRESS CHANGE

In order for the NIC to provide better service, and because of the
phase-out of the ARPANET, the following changes have taken place and
are effective immediately (6 April 1990).

NIC.DDN.MIL
  The new address for host NIC.DDN.MIL is 192.67.67.20.

  The old ARPANET address for the NIC, 10.0.0.51, is no longer
  available, due to the phase-out of the ARPANET.

  The old MILNET address for the NIC, 26.0.0.73, will continue
  to be valid until 1 June 1990, after which service to this address
  will be discontinued.

ROOT DOMAIN SERVER
  The NIC's root domain server will run on a new host,
  NS.NIC.DDN.MIL at address 192.67.67.53.

  The old root server will continue to run on NIC.DDN.MIL
  until 1 June 1990.

New host tables and domain server files produced by the NIC will
reflect the new addresses.

Users should update host tables, domain server boot files, 
manuals, and documentation to reflect the new addresses.
