This patch updates the ranges with what was missing or otherwise incorrect. 100.64.0.0/10 is left alone, for now, as it's been made special in [1]. The _address_exclude_many() call returns 8 networks for IPv4, 121 networks for IPv6. [1] https://github.com/python/cpython/issues/61602 * GH-65056: Improve the IP address' is_global/is_private documentation (GH-113186) It wasn't clear what the semantics of is_global/is_private are and, when one gets to the bottom of it, it's not quite so simple (hence the exceptions listed).
