A device can send NS messages to detect whether the IPv6 address to be configured has been used by another device. Therefore, the number of duplicate address detection attempts refers to the number of times NS messages are sent. Duplicate address detection is implemented using NS and NA messages. Duplicate address detection is implemented in a similar way as gratuitous ARP in IPv4.
