Subject: [manet] About IP Address Autoconf

Hello

I have some questions about the IP Address Autoconf IETF Draft.

1. Is it possible for some intermediate node "X" to send a particular message like "ADDR_FOUND" in response to an AREQ message, which is requesting an IP Address that is already used by some node in the network. This message will be sent by the node X if it is having some communication with that IP Address. This will be helpful in very quick Duplicate Address Detection. It will also save time which is otherwise wasted in sending the request for the same packet AREQ_RETRIES time.

2. What happens when the temporary IP Address chosen by a node is already taken by some other node which is also doing DAD. Is there a some special method to obtain that IP Address? I know the probability is less. But, still it can happen and what are the actions taken at that time? 

Any comments ???

Regards
Ankur
