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.

The following is a tabulation of socket numbers together with the
services offered. This listing is presented as an aid to network
users. If you know of a socket function which has been left out or
an entry which should be corrected or deleted please contact:
