Hi Bernie,

Assume IPv6 lease time is 100s, and IPv4 lease time is 200s. Then the 4o6
Client receives a Server-Unicast option (which may contains 10 unicast
addresses) every 100s, and a Server-Unicast option (which contains 1
unicast address) every 200s. I think it adds more complexity for client to
deal with the same option from different servers (DHCPv6 / DHCP4o6).

Cong
