SUBJECT: NSF Transition and New Default Gateway Assignment

REQUEST NODE SITE COORDINATORS AND HOST ADMINISTRATORS DISSEMINATE THIS
INFORMATION TO ALL DDN USERS

1. Please be advised that the National Science Foundation (NSF) will no
longer provide Internet network services effective May 1995. Internet
services will be provided by four commercial vendors and this
transition will have an impact on DoD users. As a result of these
changes, the PILOT Net will no longer advertise network 140.222.0.0
as a default network.

2. To minimize any disruption in network services, REQUEST DDN USERS
CHANGE THEIR DEFAULT NETWORK ASSIGNMENT FROM 140.222.0.0 to 137.209.0.0
AS SOON AS POSSIBLE, BUT NOT LATER THAN 28 APRIL 1995. Please note that
if the default network assignment is not changed, users will no longer
have access to the Internet.

3. Please refer any technical questions to the DISA-Columbus Regional
Control Center, DSN 850-8175/COMM (614) 692-8175.
