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.

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