In the DHCPv6 stateless autoconfiguration solution, hosts do not need to send any DHCPv6 packets.
In DHCPv6 stateless autoconfiguration, while hosts can generate their own IPv6 addresses using stateless address autoconfiguration (SLAAC), they still need to send DHCPv6 packets to obtain other configuration details such as DNS server addresses. Hence, the statement that hosts do not need to send any DHCPv6 packets is false.
The Information-Request is sent by the clients to the "All_DHCP_Relay_Agents_and_Servers" mutlicast address following which servers respond with a replay message containing the configuration information for the client. When using SLAAC, a host actually makes use of three different tools to find its four IPv6 settings SLAAC itself focuses on the IPv6 address only. The host then uses NDP messages to learn both the prefix length and the IPv6 addresses of the available routers on the link. Finally, the host makes use of stateless DHCP to learn the IPv6 addresses of any DNS servers.
