The list of hosts was taken from the NIC hostname table of 31-Dec-82.
The tests were run on 25-Jan-83 from ~10:00 am to ~6:30 pm PST.
Dead, refused, and unreachable hosts were retried 26-Jan-83 from ~8:00 am
to ~6:10 pm PST.
Claims are taken from the NIC host table:
T = tcp (no particular services mentioned)
t = tcp/telnet
f = tcp/ftp
s = tcp/smtp
Results for each service:

refused
unreachable
dead
accepted
