  All of your temporary privacy addresses will be coming out of the same subnet, so it’s clear they all belong to the same people.

  Ultimately the privacy extensions are just bringing IPv6’s privacy back in line with IPv4, because without the privacy extensions every single device has a separate IPv6 address based on its MAC address whereas in IPv4 most consumer networks have every device sharing a single IP.

  Every single one of those temporary IP addresses has the same prefix, which traces back to you.

    That assumes that the prefix is static which it isn’t. It also assumes that you are the only one with that prefix which isn’t necessarily the case. It makes it much harder to track compared to a static IP that is tied to your device.

    If you are the only one using a static prefix then it is less useful but chances are that prefix is shared among lots of users and devices.

    Yes and no. The deal is your last part is your MAC. So when your extension changes they can still track you over any ipv6 connection. The privacy extension changes the last bit so you can’t be tracked over any connection.

      the whole point of privacy extensions is that it replaces the MAC with a random something

  If anything just that it will break most tracking and surveillance systems that weren’t built for the tiny proportion of ipv6 hosts.

  The question is, how can get a few tens of thousands of completely random and unrelated ipv6 addresses and pick one at random for every connection I make to outside my LAN

    They are related but the prefix is shared unless you at some with your own router. (Even then your prefix probably isn’t static)

      Well, I would like the whole address, from hour to hour, to have no correlation whatsoever, as many random numbers as possible.

        That probably isn’t possible since routing on the public internet wouldn’t work.
