when i read in document 3.5.1,run the example in ipaddress.address_exclude function >>> n1 = ip_network('192.0.2.0/28') >>> n2 = ip_network('192.0.2.1/32') >>> list(n1.address_exclude(n2)) I got: Traceback (most recent call last): File "", line 1, in File "C:\Python 3.5\lib\ipaddress.py", line 794, in address_exclude s1, s2 = s1.subnets() ValueError: not enough values to unpack (expected 2, got 1)
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.
I propose a patch simply add one to end so that the broadcast address network will appear in the result, which behaves the same as ipaddr.py. Corresponding tests are added. All tests are passed but I am afraid some logic may break.
