Re: My Personal IPv6 Beef
I do this with SLAAC. Either accept that the bottom 64 bits will be generated from the server's MAC address, or look for token support in your OS of choice (`ip token` on Linux).
You then advertise the prefixes you want via RA - you can advertise multiple prefixes, so you advertise the fixed ULA prefix, and the dynamic global prefix - and the OS will generate multiple addresses, one for each prefix.
