NDP(Neighbor Discovery Protocol) A TCP/IP protocol used to obtain a node's physical address in the IPv6 addressing system. NDP is the IPv6 counterpart to the ARP protocol in IPv4 addressing. NDP broadcasts a "neighbor solicitation" message out on the network containing the destination IP it wants to reach, and the node with that IP returns its MAC address. See ARP and IPv6.
