As far as I can tell, I have the same IPv6 prefix for at least a year. Of course, if the prefix's changed, I'll have to reconfigure the homelab. If that started to become annoying I would automate that with an ansible task. But will probably need to search for a better and more stable solution.

I've tried to set up PD but it didn't work, so I've moved on with other options. Now, after you mentioned that, this feels like a good excuse to delve into what exactly didn't work back then.
