Have we figured out good ways to gracefully handle prefix changes via DHCP6-PD. I'm kind of worried of my provider changing my prefix "from under my feet" and breaking firewall rules, or worse. Also my ISP blocks some ports incoming lst time I checked, even on IPv6, even on their business plans, without a static IP. And I assume they would do the same with v6 because they don't support static prefixes themselves. To be fair their IPv4s are very static and only change when I change my WAN MAC address or am offline for longer than a DHCP lease (power outage)
