Which of the following types of IPv6 address assignments does DHCPv6 support?

 DHCPv6 supports three types of IPv6 address assignments:

Individual address assignment (IA_NA): This is the stateful mode of DHCPv6, where the DHCPv6 server assigns a normal IPv6 address to a client that can be renewed or released. The address is chosen from a pool of prefixes configured on the server and is unique and non-duplicate. The client can request one or more addresses using the IA_NA option in the DHCPv6 messages1

Temporary address assignment (IA_TA): This is similar to the IA_NA mode, but the addresses assigned are temporary and cannot be renewed or released. The temporary addresses are used for privacy reasons and are generated by the client using a random interface identifier. The client can request one or more temporary addresses using the IA_TA option in the DHCPv6 messages2

Prefix delegation (IA_PD): This is the mode where the DHCPv6 server delegates a whole IPv6 prefix to a client, such as a router or a host, that can use it for further subnetting or routing. The client can request one or more prefixes using the IA_PD option in the DHCPv6 messages. The delegated prefixes are also chosen from a pool of prefixes configured on the server3
