RFC 835: Who talks TCP?   Network Working Group D. Smallberg Request for Comments: 835 December 1982 Who Talks TCP? The list of hosts was taken from the NIC hostname table of 2-Dec-82. The tests were run on 28-Dec-82 from ~12:01 pm to ~8:10 pm PST. Dead, refused, and unreachable hosts were retried 29-Dec-82 from ~8:00 am to ~7:40 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: blank (not accepted) refused unreachable dead
