nboubakr / subnet.py

Created December 20, 2012 11:23

A simple python script converts a Classless Inter-Domain Routing (CIDR)-formatted IP address into an IP range and netmask.

	#!/usr/bin/env python
	# python subnet.py 200.100.33.65/26

	import sys

	# Get address string and CIDR string from command line
	(addrString, cidrString) = sys.argv[1].split('/')

	# Split address into octets and turn CIDR into int
	addr = addrString.split('.')
