In our spec, we mentioned that EUI-64 IID based LL address is only used. But, I think that stateful or manually configured addresses are also useful because these kinds of addresses are supported by DAD. > Second, the EUI-64 does not guarantee the uniqueness of the method. > Otherwise we would not be needing DAD with addresses that are > generated with EUI-64. Right. The EUI-64 itself is not unique. So, DAD procedure is needed for link-local address. And also stateful or manually configured addresses are used after DAD processing. > But it is mandated by the specs. So > these addresses are > *not* truly, completely, totally, unique. In our spec. The uniqueness of LL unicast address is verified by DAD procedure. And then, EUI-64 IID (or other) is extracted from LL Unicast address. Therefore, our method supposes that LL unicast address should be verified by DAD procedure.
