WebThe Neighbor Discovery (ND) protocol is used by hosts and routers for mutual discovery on locally connected nets [RFC 2461]. This protocol replaces two protocols in IPv4. One of these protocols, no longer needed in IPv6, is ARP. In IPv4, ARP was used to map an IP address to a link layer address.
