Hi Keshava,
DAD is intended to cover all unicast addresses (all scopes).
It includes an optimization, however, that allows nodes that
have checked a link-local address with a particular
Interface ID (IID) to skip checking other addresses that
are constructed on the same interface using that same IID.
DAD is a link-local mechanism (uses link-local multicast
packets). So, while it checks all addresses, it only
explicitly checks for duplicate addresses on the local link.

I would like to know
Duplicate Address detection (DAD) scope is only for
link - for link local address
Or it appilies even for
site - for site local address
global - for global unicast address.
Thanks
