Final answer:
ICMPv6 does not include all Neighbor Discovery Protocol (NDP) messages.
Step-by-step explanation:
FALSE, ICMPv6 does not include all Neighbor Discovery Protocol (NDP) messages.
ICMPv6 (Internet Control Message Protocol version 6) is a network layer protocol of the Internet Protocol Suite that is used for diagnostic and error messages. It does not include all NDP messages, which are part of the IPv6 Neighbor Discovery Protocol.
NDP is responsible for the following functions in IPv6: Neighbor Discovery, Address Autoconfiguration, Router Discovery, and Duplicate Address Detection.
