Re: [dhcwg] DHCPv6 client implementation

Tina - Operation of DHCPv6 is entirely independent of stateless address 
autoconfiguration (SLAAC) and manual address assignment, so the DHCPv6 
client should not make any changes to any addresses assigned through SLAAC 
or manual assignment.

RFC 2461 and RFC 2462 address the relationship between DHCPv6 and stateless 
address autoconfiguration.  In summary, SLAAC and the use of DHCPv6 are 
managed independently, and the protocol standards allow a host to use both 
SLAAC and DHCPv6 simultaneously.  I don't remember if the RFCs explicitly 
mention that both SLAAC and DHCPv6 are also independent of manual address 
assignment.
