Yes - that's reasonable.

I think you still need to support the common notations:
Address('10.0.0.1') # .network == None
Address('10.0.0.1/255.255.255.0')
Address('10.0.0.1/24')
>We could also have some_network[n] return an Address

Yes.
(Of course, we're simplifying - there would really be classes for each
protocol).
