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

Project description

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


Install Django Allow CIDR:

pip install django-allow-cidr

Add the Middleware to your MIDDLEWARE_CLASSES (for Django < 1.10) or MIDDLEWARE settings. It should be the first in the list:


Add the ALLOWED_CIDR_NETS setting:




  • 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?
