Hi Ying, all,

You can also find an example solution briefly described in the following
I-D:

http://tools.ietf.org/html/draft-mutaf-dhoa-00

But protocols are necessary for securely distributing disposable home
addresses to correspondent nodes.

For further discussion you may subscribe to humanresolvers.

Thanks,
