I mean, eg, IPv4Network.fromHostIP('192.168.1.1/24').

I'd actually suggest to use

net, host = parse_network_and_host("192.168.111.33/24") (IPv4Network('192.168.111.0/24'), IPv4Address('192.168.111.33'))

I think this helps the use case of the short network+gateway notation, while keeping the concepts of network and host address cleanly separate.

I would have IPv4Address itself be strict, and thus the new constructors would compute the network address and call the regular IPv4Address constructor.(*)

Then the regular IPv4Network constructor could be strict and can be used for validation.
