Who Talks ICMP, too?
Survey of 18 February 1983
A survey was undertaken to determine how many hosts are able to
respond to TELNET 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 RFC843, extracting only those
hosts which are listed there as accepting TELNET connections.
The tests were run on 18-Feb-83 from 3 PM to 6:30 PM EST
from a terminal concentrator located at 192.1.2.22, at BBN.
This net (192.1.2.xxx) is connected to the internet through
a routing gateway, and this terminal concentrator speaks ICMP
including redirection and reporting to the user.
The connection attempts were done manually by typing the
dotted form addresses, so only three passes were made through
the table of hosts. Therefore a few may have been missed due
to being down at these times.
Summary information:
