[6bone] DAD scope ??

| There seems to be some confusion here.  DAD is used to guarantee
| uniqueness of an address on a _link_ (or possibly on a subnet) -- the same
| for any kind of address, not uniqueness within a scope (e.g. DAD for a
| global address does not mean it's globally unique).

DAD for a global address does not mean it's globally unique, but that
the address is not in use by other devices on the link. I see your
point.

Taken that way, DAD is performed using the linklocal scope, but FOR
any given scope.

Makes sense :)
