Django Allow CIDR

A Django Middleware to enable use of CIDR IP ranges in ALLOWED_HOSTS.

Quickstart

Install Django Allow CIDR:

pip install django-allow-cidr

Add the Middleware to your MIDDLEWARE settings. It should be the first in the list:

MIDDLEWARE = (
    'allow_cidr.middleware.AllowCIDRMiddleware',
    ...
)

Add the ALLOWED_CIDR_NETS setting:

ALLOWED_CIDR_NETS = ['192.168.1.0/24']

Profit!

Features

  • The normal ALLOWED_HOSTS values will also work as intended. This Middleware is intended to augment, not replace, the normal Django function.
  • If you do define ALLOWED_CIDR_NETS and it has values, the middleware will capture what you have in ALLOWED_HOSTS, set ALLOWED_HOSTS to ['*'] and take over validation of host headers.
  • The ALLOWED_CIDR_NETS values can be any valid network definition for the netaddr package.

Running Tests

Does the code actually work?

source <YOURVIRTUALENV>/bin/activate
(myenv) $ pip install tox
(myenv) $ tox

Pushing to PyPI

Cutting a new Github Release will trigger CI checks, followed by an automatic release to PyPI, using the release version. Please make sure that your Github Release version matches the project version in __init__.py.

For more details see the release job in .github/workflows/ci.yml.
