12. Management of Temporary Addresses

12. Management of Temporary Addresses

A client may request the assignment of temporary addresses (see RFC 3041 [12] for the definition of temporary addresses). DHCPv6 handling of address assignment is no different for temporary addresses. DHCPv6 says nothing about details of temporary addresses like lifetimes, how clients use temporary addresses, rules for generating successive temporary addresses, etc.

Clients ask for temporary addresses and servers assign them. Temporary addresses are carried in the Identity Association for Temporary Addresses (IA_TA) option (see section 22.5). Each IA_TA option contains at most one temporary address for each of the prefixes on the link to which the client is attached.

The IAID number space for the IA_TA option IAID number space is separate from the IA_NA option IAID number space.

The server MAY update the DNS for a temporary address, as described in section 4 of RFC 3041.
