Check if two CIDR addresses intersect?

Question

Given two CIDR addresses say 192.168.2.0/14 and 192.168.2.0/32

How do I check if two ip addresses overlap in "python2.6"??

I have gone through netaddr and it allows to check if 192.168.2.0 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"):

But how to check for two CIDR address??

I found a reference :: How can I check if an ip is in a network in python

Answer 1

Using ipaddr:

>>> 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
