DESCRIPTION
ICMPv6
Internet Control Message Protocol for IPv6 (ICMPv6 or ICMP for IPv6) is defined in RFC
4443. ICMPv6 has a preceding Next Header value of 58, which is different from the
value used to identify ICMP for IPv4. ICMPv6 is an integral part of IPv6. IPv6 nodes use
ICMPv6 to report errors encountered in packet processing and perform other diagnostic
functions, such as "ping".
