What is the IPv6 multicast address used by DHCPv6 clients on the local link?

Explanation:
DHCPv6 uses a specific link-local multicast group to reach DHCP servers on the same network segment. When a client starts, it sends its SOLICIT message to the all-DHCP-servers-and-relays group, which is ff02::1:2. This ensures every DHCPv6 server or relay agent on the local link receives the request, while the scope remains local to that link. Other well-known link-local groups exist (such as ff02::1 for all nodes or ff02::2 for all routers), but they’re not used for locating DHCPv6 servers. So the correct multicast address is ff02::1:2.
