D-link support response is "yes, our > MAC-addresses are not unique enough". I'm missing something that is probably obvious. Doesn't the home modem, or "residential gateway," have hard-coded in it the unique IPv6 prefix for each home? If yes, then why would a home PC host not always have a unique IPv6 address, even if the MAC address might be duplicated in some other home on the broadcast domain? And why would ND conducted inside a home go beyond the "residential gateway"? I think I understand the problem being addressed here, but it seems to apply only if all the homes passed by the "last mile" broadcast domain is using the same IPv6 prefix.
