+Request for Comments:  844                            February 1983
+
+
+		   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.
+
