To be explicit though, unless I'm drastically misreading what you're asking for, I consider the design you're proposing to be broken from a usability perspective (striving for academic/pedantic correctness over accepted practice).

It is certainly not academic correctness, it is concern over the understandibility of the library. The behaviour you are proposing is confusing, and even if you think it is more practical (which I doubt it is), it should still be avoided IMO. While "192.168.1.2/24" may be an accepted notation in some situations, it is not a notation for a network but for an (address, mask) pair, or an (address, network) pair.

There was a proposal to have a separate parse_address_and_mask method which would return a (Address, Network) tuple, I still don't know why you don't seem to consider it seriously, rather than trying to make the Network class a kind of all-in-one type conflating different concepts.

Regards

Antoine.
