NETWORK HOST STATUS

        This RFC reports on the status of most Network Hosts from April
   24 to May 5.  During this interval the IBM 360/44 at the University
   of Southern California (Network Address 23) became a Network user.

This RFC reports on the status of most Network Hosts from April 24 to May 5. During this interval the IBM 360/44 at the University of Southern California (Network Address 23) became a Network user.

        Several Hosts are currently excluded from the daily testing.
   These Hosts fall into two categories:

Several Hosts are currently excluded from the daily testing. These Hosts fall into two categories:

        1) Hosts which are not expected to be functioning on the Network
   as servers (available for use from other sites) on a regular basis
   for at least two weeks.  Included here are:

   Included here are the Terminal IMPs, which are presently in the
   Network (AMES, MITRE, NBS, ETAC, USC, GWC, and BBN*).  This category
   also includes the Network Control Center computer (Network Address 5)
   which is used solely for gathering statistics from the Network.
   Finally, included among these Hosts are the following:
