Neighbor Discovery (ND) Protocol

Neighbor Discovery (ND) protocol uses messages and other means to discover the physical ad- dresses and much more about computers and routers on a network. ND protocol enables a more extensive range of information to be determined beyond the capabilities of ARP. This includes physical addresses, configuration information, and the address prefixes of other hosts. Also, ND protocol can determine the location of nearby routers and whether a computer or router can be currently reached. ND protocol additionally provides information about whether a physical ad- dress has been changed, such as when a network interface is replaced. IPv6 replaces the use of ARP with the use of ND protocol for a more effective discovery process.
