Who talks ICMP, too? - Survey of 18 February 1983
Overview
RFC 844, “Who talks ICMP, too? - Survey of 18 February 1983”, is an Unknown document published in February 1983 by R. Clements. It updates RFC 843. The canonical text is published by the RFC Editor.
Abstract
This survey determines how many hosts are able to respond to TELENET connections from a user at a class C site. This requires, in addition to IP and TCP, participation in gateway routing via ICMP and handling of Class C addresses. The list of hosts was taken from RFC 843, extracting only those hosts which are listed there as accepting TELNET connection. The tests were run on 18-Feb-83.
What “Unknown” means
The standards-track status of this early RFC was never formally classified.
