And the Fritz!Box contains a pre-provisioned config with IPv6 enabled?

We have it enabled on the BRAS for all Customers - customer simply have
to use a single click in the CPE - for now its all AVM world ...

It might be surprising for customers to see their Home Electronics get
v6 connectivity. I personally had astonishing side effects at home e.g.
not beeing able to print anymore due to v6 connectivity because cups
forgot to listen on the v6 address and v4 fallback of the cups client
not working as expected.

Enabling it without user interaction for the home LAN might cause
effects like this and i'd like to hear experiences.

The residential customers LAN is the most heterogeneous network in the
world and most likely contains the most embedded and untested v6 stacks
you'll find together in one network - so breakage is expected.
