I was alluding that I would implement DHCPv6-PD in (probably) rad(8) if
ziggo stopped to be stupid. Or their cpe stopped to be stupid. I.e. the
way things get done in OpenBSD: Someone has a use case and the means to
do something about it. I have the means but no use case.

I'm currently using it with slaac so I have a single collision
domain, but all my devices get native IPv6 from a single /64.

They are not speaking DHCPv6 at all. I can login to the CPE and switch
from slaac to dhcp. Which is pretty much nonsensical. The effect is that
slaac stops working and the dhcp server tells me: no lease or something
to that effect.

There are some forum posts, all in Dutch, of people who try to argue the
finer points of IPv6 with ziggo support - which unsurprisingly isn't
going anywhere.

In my defence, I have been left unsupervised.
