Since docker wants to manage the IP addresses itself, I can not give it the
entire subnet.
That would also be wrong in many ways. So I must give it part of the subnet to
use.

--subnet=10.0.1.0/24 \

no matching subnet for gateway 2a00:1098:8:bf::2
* What exactly did you do (or not do) that was effective (or
ineffective)?
Unresolved.
* What was the outcome of this action?
the network is not created
* What outcome did you expect instead?
the network should have been created.
Docker thinks that IPv6 works like IPv4, and it does not.
The default gateway in IPv6 can be anything, and is often an IPv6 Link-Local
address (scoped to that interface).
There is no requirement that the addresses be on-link, so it is entirely
reasonable to specify a gateway that is
not within the provided subnet.
