django-netfields
Django PostgreSQL netfields implementation
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has no known vulnerabilities, and solves a real problem—efficient network data handling in Django+PostgreSQL. Install if you need to store or query IP/CIDR/MAC data; skip if you're not using PostgreSQL or don't need network-specific lookups.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires PostgreSQL backend; psycopg2 or psycopg driver must be installed separately.
- Django >= 1.11 required.
- Low friction: pure Python wheel with only netaddr and django as runtime dependencies.

What it is and what it does
django-netfields extends Django's ORM with proper PostgreSQL network data types, replacing the inefficient built-in IP fields with native INET, CIDR, MACADDR, and MACADDR8 field types. The package maps these PostgreSQL types to Python's ipaddress module (for IP fields) and netaddr.EUI (for MAC fields), eliminating costly HOST() casts in queries and enabling IPv6 support.
The package includes NetManager, which unlocks advanced network-based lookups directly in the ORM—containment checks, overlap detection, family matching, prefix length filtering, and more—corresponding to PostgreSQL's native network functions. It also exposes Postgres network functions (Family, Masklen, Broadcast, etc.) as Django database functions for complex queries and annotations.
Use it for
- Store and query IP addresses and subnets efficiently in Django models backed by PostgreSQL
- Perform network containment and overlap queries without application-level filtering
- Track MAC addresses in network device or inventory models
- Build IP-based access control or firewall rule systems with native database queries
- Annotate models with extracted network metadata (family, netmask length, broadcast address)
