I should note that I've softened my position slightly from what I posted
yesterday. I could live with the following compromise:

>>> x = IPv4Network('192.168.1.1/24')
>>> y = IPv4Network('192.168.1.0/24')

>>> x == y # Equality is the part I really want to see changed
True

>>> x.ip
IPv4Address('192.168.1.1')
>>> y.ip

IPv4Address('192.168.1.0')

With those semantics, IPv4Network objects with distinct IP addresses (but the same network) could no longer be stored in a dictionary or set. IMO, it is a little counter-intuitive for objects to compare equal yet have different properties. I don't think this is a good compromise.
