I would expect that this is different with 

http://www.ietf.org/rfc/rfc4862.txt
4862 IPv6 Stateless Address Autoconfiguration. S. Thomson, T. Narten,
     T. Jinmei. September 2007. (Format: TXT=72482 bytes) (Obsoletes
     RFC2462) (Status: DRAFT STANDARD)

http://www.ietf.org/rfc/rfc4941.txt
4941 Privacy Extensions for Stateless Address Autoconfiguration in
     IPv6. T. Narten, R. Draves, S. Krishnan. September 2007. (Format:
     TXT=56699 bytes) (Obsoletes RFC3041) (Status: DRAFT STANDARD)

In both cases, the addresses are concocted by the system using them. For RFC 
4862, that means "when the system receives a new prefix in an RA". My 
understanding is that Windows privacy addresses are generated daily and held 
for a week; I would expect other implementations to do something akin to that. 
I wouldn't not expect DHCP servers to be doing updates in a world in which the 
end host calculates its own address.

Do we know about that at all?
