Re: ICMP Well-Known Port

[Bill_Royds () pch gc ca]

ICMP is a protocol not a service. It is on par with TCP or UDP. TCP and USP are
prtocols that have services identified by ports, not ICMP.
That said, ther are ICMP  packet type codes which distinguish different ICMP
message formats.

Evidently I'm really missing the boat.  I've been trying to find the
well-known port for ICMP.  Is there no such thing?
