Xiang Zhang added the comment: In old ipaddr.py, IPv4Network('192.0.2.0/31').subnet() returns [IPv4Network('192.0.2.0/32'), IPv4Network('192.0.2.1/32')], but ipaddress returns only [IPv4Network('192.0.2.0/32')].
It seems simply change end to end+1 in https://hg.python.org/cpython/file/tip/Lib/ipaddress.py#l921 can solve the problem and pass the test. But maybe there are some side effects. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26457> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
