Which ICMPv6 type is Neighbor Advertisement?

Explanation:
In IPv6, address resolution and neighbor discovery use ICMPv6 messages to map IPv6 addresses to link-layer addresses. The message that carries or updates that binding is the Neighbor Advertisement. It can respond to a Neighbor Solicitation with the learned mapping or announce its own address-to-MAC binding to refresh caches. This is distinct from Echo Request/Reply, which are used for ping testing, and Neighbor Solicitation, which is the request to learn a neighbor’s link-layer address. So the one called Neighbor Advertisement is the ICMPv6 type used for advertising the address mapping.
