Given a IPvNetwork network if x in network: ... raises an AttributeError instead of returning False. |

It is not obvious that this is a bug. Why should None be a valid value for 'in network'? |

I agree with David. And since the PR says "not other", then it makes even less sense, since it's checking for any False-y object. I recommend closing this as "not a bug". |

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.
