What is DHCPv6 used for when a network is configured for Stateless Address Autoconfiguration (SLAAC)?

Stateless Address Autoconfiguration (SLAAC) allows for the client to learn the network ID and calculate a host ID that is unique. However, SLAAC lacks the ability to configure options such as DNS time servers. DHCPv6 allows for the configuration of these options when used in conjunction with SLAAC. DHCPv6 configured for SLAAC is not used for stateful configuration of client IPv6 addressing. DHCPv6 configured for SLAAC will not provide network IDs. IPv6 by default provides stateless configuration of clients with IPv6 addressing; DHCPv6 complements this stateless configuration.
