[issue20825] containment test for "ip_network in ip_network"

[Antoine Pitrou]

Antoine Pitrou added the comment:

I don't think "in" is the right operator for this. You can draw an analogy with sets:

>>> a = {1,2}
>>> b = {1,2,3}
>>> a <= b
True
>>> a in b
False

In mathematical terms, there is a difference between inclusion (being a subset of) and containment (being an element of).
