        @jhg They can be set on the DHCP6 Server tab under DHCPv6 Static Mappings. One can use Status/DHCPv6 Leases and click the [+] icon to add the mapping.

        In the pool you can use something like "::1000" to "::2000" or "::ffff" or whatever and that uses the beginning of the prefix, ending with that range.

        However many devices/browsers/programs use temporary IPv6 addresses so one can be assigned but it will likely use others.

        Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
        When upgrading, allow 10-15 minutes to reboot, or more depending on packages, and device or disk speed.

          With SLAAC, you have one address that does not change. If you want a specific address, you can assign a MAC address that will provide that address. This will require using the MAC address to generate the consistent address, rather than a random number.

          I haven't lost my mind. It's around here...somewhere...

            @JKnott I guess my question wasn't well phrased. I'll post a rephrased version as a new question and delete this question in a few hours.
