A possible compromise then:
Just change the definition of network equality to only consider the
network address and ignore the ip attribute. Optionally provide a
separate comparison method that pays attention to the ip attribute
(keeping in mind that it isn't particularly hard for people to write out
"net1 == net2 and net1.ip == net2.ip" if they care about the extra state).
Then "IPNetwork" can be largely documented as a true IP network
definition, with the "Host with Netmask" use case handled by having an
IPNetwork object with "net.ip != net.network".
Regards,
Nick.
