Hi, Warodom.

I'll answer your question as inline.

         I thought, we could use DHCPv6 [if it has] do same processing with
your draft-propose,are we?
==> yes, you're right.
How about performance of use DHPCv6 VS your draft?
==> I think my solution is better and more suitable to HMIPv6 in the respect of the resolution time.
==> If we use DHCPv6, our mobile nodes should send DHCP request message to get the information
==> of recursive DNS server. But when we use my solution, we need not to send a request message,
==> because our mobile nodes get MAP option message with recursive DNS server's address in a new MAP domain.
