 Subject:             Renaming of Domain DCA to DISA
     
 1.  Since the Defense Communications Agency (DCA) has recently changed its
     name to Defense Information Systems Agency (DISA), it is necessary to 
     change the DCA domain name to DISA.  Accordingly, all DDN hosts using
     the .dca.mil extension must be changed to .disa.mil., with the exception
     of hosts that should have the extension .ddn.mil.  These hostnames will
     be changed at the same time the DISA changes are made.
     
 2.  The NIC will make these changes globally for all hosts registered
     under the .dca.mil domain; the changes will take effect on 31 March 1992.
     All host administrators and/or host coordinators will be responsible for 
     ensuring that they make any host modifications necessary to accommodate
     this change and for promptly notifying all the users associated with their
     hosts about the change.
     
 3.  DDN will retain the DCA.MIL name as a nickname or alias for a period of
     one year to allow for an easy transition from the DCA.MIL domain to the
     DISA.MIL domain.  

 4.  Any questions concerning the change of hosts from .dca.mil to .disa.mil
     should be directed to Mr William J. Hamill, DISA Milnet Domain Manager,
     (703) 487-8405.
     
 5.  Any questions concerning the change of hosts from .dca.mil to .ddn.mil
     should be directed to the MILNET manager in the appropriate geographic 
     area:
