> in Germany we have the peculiar horror of getting the IPv6 address and all delegated prefixes changed on every redial.

This is oh so very German.

In normal times it is massively overkill. I have to wonder if, heaven forbid, the things these sort of German things are meant to mitigate come to pass again if they will make any difference or if they are a largely symbolic act designed to demonstrate ideological opposition to such things.

This seem to be common. My RSP (ISP) only offers a fixed IPv6 address/prefix on request -- otherwise they will just allocate one out of their pool as they do for dynamic IPv4 (although both dynamic IPv4 and IPv6 is fairly sticky so normally DHCP/PPPoE connections will get the same address previously used as long as it hasn't been reallocated). I personally have a static IPv4 address and a static IPv4 address/prefix from my RSP for my home network.

Got the same here in Norway. I've had the same dynamic IPv4 address from my ISP since I moved here over 6 years ago. I get a new IPv6 prefix every time the line goes down, modem needs reboot, moon is full etc.

My IPv6 prefix changes several times a day with no apparent reason.
