 SUBJECT:      Elimination of Selected Networks from MILNET Core Gateways

 Preparer:     Ted A. Tatchio, Maj, USAF, 2-7580

 1.  Due to the rapid addition of MILNET and NSFNET networks, MILNET is again
     approaching the limit of the number of networks the Butterfly mailbridges
     can advertise (3750).  To manage this situation, DISA will restrict the
     advertising of selected foreign commercial and foreign educational
     networks.  This includes the following networks:

     128.134
     128.184
     128.250
     129.78, 129.94, 129.96, 129.127, 129.180, 129.249, 129.254, 130.34,

     These networks WILL NOT be accessible from MILNET.  If you need
     access to any of these networks, please contact the MILNET MC trouble
     desk.  They will open a problem report and coordinate this request with
     the MILNET Manager.  In such cases, DISA will need a brief explanation
     of the requirement to approve the inclusion of individual networks.

 3.  Implementation of this action will begin on 11/Mar/92 and be completed
     no later than 13/Mar/92.

 4.  Additional networks may be eliminated as the need arises.

 5.  DISA POC is Maj Ted A. Tatchio, DNS 22-7580, com'l (703)692-7580.
