Neighbor Advertisement

A Neighbour Advertisement message is part of the ICMP protocol. It is used heavily with IPv6 and the NDP protocol.

NA messages are sent in response to the Neighbour Solicitation message. For example, if one device wants to find another device, or if it’s checking for IP conflicts.

The Neighbour Advertisement message includes the information that was originally requested.
