Subject: Question about DAD..

Dear All,

I am confused on when the DAD(Duplicate Address Detection) should be perfomed!
I had the impression that, it would do so when address assignemnt(MADHCP or stateless MADDRCONF) is performed.
Should DAD be performed whenever any node establishes a new link with any other node in the MANET? 
	
If yes, since DAD is performed (either in distributed or centralised fashion) upon initialization and ensures that there are no duplicates, is there any possibility that there will happen a duplicate during operation? Or, my question seems to have some logic when the MANET is connected to the Internet? (where at this point the source of address assignment is able to run DAD for the MANET(i.e., locally) but can not ensure duplicates with the rest of the world!?)

Finally, can anybody suggest some source for Appletalk operation. I am interested in the address assigment part...

Thanks in advance!

George A.
