Dear Tom, Thanks for the comment.
There is some text in the Sec 9 in draft-ietf-dhc-dhcpv4-over-dhcpv6-09, which may be related to this: If the IPv6 configuration that contained the 4o6 Server Address option subsequently expires, or if the renewed IPv6 configuration does not contain the 4o6 Server Address option, the client MUST stop using DHCPv4 over DHCPv6 to request or renew IPv4 configuration. However, the client continues to request 4o6 Server Address option in the messages sent to the DHCPv6 server as long as it desires to use DHCPv4 over DHCPv6. So if a CE changes the binding IPv6 address in the context of normal DHCPv6 operation, it has a chance to update the information to the DHCP server.
