问题描述
给出两个CIDR地址，例如192.168.2.0/14和192.168.2.0/32
Given two CIDR addresses say 192.168.2.0/14 and 192.168.2.0/32
如何检查 python2.6中是否有两个IP地址重叠？ ？
How do I check if two ip addresses overlap in "python2.6"??
我通过netaddr，它可以检查
192.168.2.0是否在CIDR地址192.168.2.0/14中，
I have gone through netaddr and it allows to check if192.168.2.0 is in CIDR address 192.168.2.0/14 by
from netaddr import IPNetwork, IPAddress
bool = IPAddress("192.168.2.0") in IPNetwork("192.168.2.0/14"):
但是如何检查两个CIDR地址？
But how to check for two CIDR address??
我找到了参考:: ::
I found a reference :: How can I check if an ip is in a network in python
推荐答案
使用：
>>> import ipaddr
>>> n1 = ipaddr.IPNetwork('192.168.1.0/24')
>>> n2 = ipaddr.IPNetwork('192.168.2.0/24')
>>> n3 = ipaddr.IPNetwork('192.168.2.0/25')
>>> n1.overlaps(n2)
False
>>> n1.overlaps(n3)
False
>>> n2.overlaps(n3)
True
>>> n2.overlaps(n1)
False
