Yes, but I would prefer to sort out the networking first.

Ah. Doesn't work without an AA though.

Can I persuade you to add a new range for the IBSS-STA XOs that are
requesting leases over IPv4? 126 addresses is not many when XOs will
be assigning them randomly, we will have kids arriving at school at
the same time, and many laptops expiring on the same day.
