      @johnpoz your right they do change the MAC addresses your right they also spoof them today. Again if a 48 mac is hard coded into a network interface there must be a way to know the differences. Vendor ID is key

        Don’t quote me on this part, I think every IPv6 has the MAC address ciphered into the address temp or not it just is masked better.

        Ooops! I quoted you! 😉

        An IPv6 address can use either the MAC address or a random number, your choice. As I mentioned, with SLAAC, you can have up to 8 global addresses. One is consistent and would be used for servers, etc.. The other 7 are always based on a random number and used when you connect to somewhere else. So, when you go to a web site, you will be using the most recent of the 7 temporary addresses.

          So, you're saying a vendor couldn't make, for example, both an Ethernet and Firewire interface? I doubt it.

            @JKnott part of the 48 bit MAC address has vendor information you can use part of the 48 bit mac and find who made the device by way of online database.

              @JonathanLee pretty sure kea dhcpv6 allows for reservation of ipv6 via mac vs duid.. If that will help you out.. at some point here that will prob make it to pfsense integration.

                  @JonathanLee its not going to do it for any IP out of the pool.. It would be for a reservation..

                  https://kb.isc.org/docs/what-are-host-reservations-how-to-use-them

                  hardware address is one of the options of the host-reservation-identifiers

                    @johnpoz maybe I should reopen it as a host reservation feature request

                      @JonathanLee not even sure why you are putting in a feature request at this point.. I would wait til kea is out of preview.. I would think since it is a clearly defined option in kea, that it would most likely be available once they out of preview mode for kea.

                        Yes, I've been aware of that for coming up on 30 years.
