IPv6 Neighbor Discovery (ND) Protocol to provide more efficient address resolution than the ARP method used in IPv4. When a host wants to get the layer two address of a datagram destination it sends a Neighbor Solicitation ICMPv6 message containing the IP address of the device whose layer two address it wishes to determine. That device responds back with a Neighbor Advertisement message that contains its layer two address. Instead of using a broadcast that would disrupt each device on the local network
