ICMPv6 Messages (Cont.)
RA messages are sent by IPv6-enabled routers every 200 seconds to provide addressing information to IPv6-enabled hosts.
RA message can include addressing information for the host such as the prefix, prefix length, DNS address, and domain name.
A host using Stateless Address Autoconfiguration (SLAAC) will set its default gateway to the link-local address of the router that sent the RA.

A device assigned a global IPv6 unicast or link-local unicast address, may perform duplicate address detection (DAD) to ensure that the IPv6 address is unique.
To check the uniqueness of an address, the device will send an NS message with its own IPv6 address as the targeted IPv6 address.
If another device on the network has this address, it will respond with an NA message notifying to the sending device that the address is in use.
