As it is, -1 from me. Either we only keep two concepts (Address and Network), or if we introduce a third one (AddressWithMask, whatever) for added practicality; but we shouldn't blur the line between the two former canonical concepts under the pretext that a platypus-like Address might be helpful in some particular situations. I completely agree with this. By keeping the concepts distinct we can catch mis-uses earlier. If needed, convenience functions (or classes, or whatever) could be layered on top. But the underlying concepts need to be clear.

That would be my view as well (this includes getting rid of the current duality of IPNetwork by dropping the ip property, only accepting the network address in the normal constructor and having a separate constructor that allows a network object to be created from an arbitrary host address and a netmask)

Is-a-2.x-str-a-sequence-of-ASCII-characters-or-a-chunk-of-binary-data?'ly, Nick.
