django-cidrfield 0.1.2

Proper CIDR fields for Django running on any database

cidrfield provides a model field for django that allows the storage of an ip network on the db side by using ipaddress to handle conversion to an ipaddress.ip_network instance (or None) on the python side. It supports the use of __contains and __in to query the IP network that contain and belong to.

Installation

Add this to your django project by installing with pip:

pip install django-cidrfield

Usage

In your models, do something like the following:

from django.db import models
from cidrfield.models import IPNetworkField

class MyModel(models.Model):

    # the regular params should work well enough here
    ip_network = IPNetworkField()
    # ... and so on

Then you can store a ip network like the following:

MyModel(ip_network='192.168.1.0/24').save()

Then you can store a ip network like the following:

MyModel.objects.filter(ip_network__contains='192.168.1.1')
MyModel.objects.filter(ip_network__in='192.168.0.0/16')
