I'd agree that 256 at home seems high to me, today... I do have 10
vlans at home but I could be considered an outlier. I'm not sure that
in the future 10 would even been considered small, maybe things split
on room levels, or appliance types or 'needs vendor support' or some
other set of arbitrary policy points. I agree with you below though
that a /48 seems very large for a residence :)
