[issue31905] IPv4Networkcontains raises exception on None

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

I concur. IPvNetwork is not a general purposed collection. And even genera purposed collections can have restrictions on the arguments of "in". E.g.:

>>> [] in {}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

Similar issue already was raised (maybe not for IPvNetwork, but for other class supporting the "in" operator) and was closed with the same arguments.
