Creating single article with description of control messages

Rather than having a separate article for each control message I think it would be better to have a single article containing them all. List of ICMP control messages would be a suitable name. Comments? reetep 19:06, 31 May 2005 (UTC)[reply]

ICMP is a supporting protocol to IP, but in the protocol stack it's relative position is higher than IP as ICMP receives services from IP.

Ghost pings

Why, when a computer crashes so badly that all other I/O screeches to a halt, TCP applications stop working, etc, will some computers still respond to ICMP packets? What is it about the ICMP implementation of any given network stack or OS kernel that would make that happen?

Transport layer control protocol

ICMP is part of the transport layer, but the Internet protocol suite sidebar lists it as being in the network layer.

ICMP will normally run on port 135

What on earth is that about?
