Another way to approach this would be for the Address object to potentially have a 'network' attribute referencing a Network object.

Yes - that's reasonable.

Then there are only two classes, but three use cases are covered:

1) a Network 2) a plain, network-agnostic Address with network == None 3) an Address with an attached Network An Address could be constructed in three ways: Address(ipnumber) Address(ipnumber, network = ) Address(ipnumber, mask = ) # constructs and attaches a suitably-masked Network instance

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 somenetwork[n] return an Address referring back to the network object it was obtained from.

Yes.

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