iptools 0.6.1

The iptools package contains a few useful functions and objects for manipulating ip addresses in Python. This was all inspired by a desire to be able to use CIDR address notation to designate INTERNAL_IPS in a Django project's settings file.

Functions:

 * validate_ip: Validate a dotted quad ip address.
 * ip2long: Convert a dotted quad ip address to a network byte order 32-bit integer.
 * long2ip: Convert a network byte order 32-bit integer to a dotted quad ip address.
 * validate_cidr: Validate a CIDR notation ip address.
 * cidr2block: Convert a CIDR notation ip address into a tuple containing network block start and end addresses.

Objects:

 * IpRange: Range of ip addresses providing `in` and iteration.
 * IpRangeList: List of IpRange objects providing `in` and iteration.

Using with Django

The IpRangeList object can be used in a django settings file to allow CIDR notation and/or (start, end) ranges to be used in the INTERNAL_IPS list.

Example:

#!/usr/bin/env python
import iptools

INTERNAL_IPS = iptools.IpRangeList(
 '127.0.0.1', # single ip
 '192.168/16', # CIDR network block
 ('10.0.0.1', '10.0.0.19'), # inclusive range
)
