len() of ipaddress.ip_network()

[Skaperen]

EDIT: This question intrigued me, so I went to github to check from rangeobject.c how len of range determined. My knowledge of C is next to none, but:

the point is that it was implemented with C types. to make it work even higher, it needed to be calling the extended precision int code, like it would have to be doing for lots of other things like actual arithmetic -or- implement just the len() part in Python and have the C code call that. i doubt len() would be called too often to consider it a critical point.

slicing a network object would be the next thing. applying [:16] or [-32:] would get a list of one network and applying [8:24] would get a list of two networks since CIDR cannot span that range. or, they implement a network range type object. they did implement the "in" operation, at least for addresses in a network. i should test if network "in" network works.

i am thoroughly familiar with networks and have implement some of this stuff in C. maybe i should implement a subclass with these many added features (just in Python, not C).
