Xiang Zhang added the comment: issue27683.patch tries to fix this. It alters the doc and refactors the constructor, so there is no difference between different arguments As for IPv6Network, it has the same problem. -- nosy: +xiang.zhang Added file: http://bugs.python.org/file44193/issu

Emanuel Barry added the comment: Ack, special cases! I can look into making a patch, but I'm not really acquainted with ipaddress or the relevant protocols, so it might not be optimal. I'll give it a shot next week if nobody else does. -- stage: patch review -> needs patch ___

Nick Coghlan added the comment: As Stephen notes, the underlying problem appears to be a behavioural difference between two theoretically equivalent ways of defining a network: >>> list(ipaddress.IPv4Network(('127.0.0.4', 31)).hosts()) [] >>> list(ipaddress.IPv4Network(('127.0.0.4/31')).hosts()

Stephen Shirley added the comment: The bug appears to be in the new form of the constructor. Here's a more minimal reproduction: In python3.5: >>> list(ipaddress.IPv4Network(("127.0.0.4", 31)).hosts()) [] In python3.4 >>> list(ipaddress.IPv4Network("127.0.0.4/31").hosts()) [IPv4Address('127.0.

New submission from tklausmann: Between Python 3.4 (3.4.5 I've tested with) and Python 3.5 (3.5.2), the behavior of ipaddress's subnet() method changed. This code: $ cat iat.py import ipaddress p = ipaddress.IPv4Network("172.0.0.4/30") subnets = p.subnets(new_prefix=31) n = next(subnets) pri
