                         Socket Number List
 This is a second pass at the specification of the socket numbers.
 More sockets have been made available for experimental functions,
 some new sockets have been assigned for network standard functions,
 host specific functions and experimental functions, and the list of
 available sockets for server hosts has been updated.
 Following are the current assignments for socket numbers used for
 public functions.  Note that a socket number is a 40 bit quantity,
 the first 8 bits being the host specification, the next 24 bits being
 site specific, and the last 8 bits being user specified -- these last
 8 bits are called the AEN [it stands for, cleverly enough, Another
 Eightbit Number].
 For the assignments here the value in the host field ranges across al
 hosts (unless otherwise specified), the value in the 24 bit field is
 zero, and the AEN is indicated here.

General Assignments:

 Sockets             Assignment
 0 - 63              Network Wide Standard Functions
 64 - 127            Host Specific Functions
 128 - 223           Reserved for Future Use
 224 - 255           Any Experimental Function

 There are several hosts performing public services on sockets which
 conflict with the above scheme.  We hope we can resolve these
 conflicts with a minimum of disruption.
