  When mobile node moves into another MAP domain in hierarchical mobile IPv6 network, 
  it needs to find a new recursive DNS server  for the optimization of DNS resolution process 
  in the respect of name resolution time.

>We can reach mobile node in new location by using name in DNS. 

  Yes, your're right. But when a mobile node tries to connect to an Internet service, such as web server,
  first of all, it should resolve the service's DNS name into IP address.
  In current DNS operation, the mobile node uses a fixed recursive DNS server normally placed in its home network.
  If the mobile node can find a new recursive DNS server in the visited network, 
  it can use the new one for DNS name resolution instead of the previous one.
  In the result, the time for name resolution can be saved. This is the main object of this draft.
  I think the idea of the draft can be applied to IPv6 or mobile IPv6 network as well as hierarchical mobile IPv6 network.

Thanks for your question.
