netaddr
A network address manipulation library for Python
Decision gist · record as of 2026-08-14
Yes. netaddr is a stable, dependency-free library for a well-defined problem (network address manipulation) with no known vulnerabilities. Its dormant maintenance is not a blocker for stable use cases; the API is mature and the task domain is not rapidly evolving. Install if you need to work with IP addresses, subnets, or MAC addresses in Python.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.7 or later.
- Low friction install with no runtime dependencies.
- Dormant maintenance (last commit 2024-07-05, 808 days since release) but marked Production/Stable; suitable for stable, well-defined network tasks rather than rapidly evolving features.

What it is and what it does
netaddr is a pure-Python library for parsing, representing, and manipulating network addresses at Layer 2 and Layer 3. It handles IPv4 and IPv6 addresses, subnets, and masks; MAC and EUI-64 identifiers; and provides utilities like CIDR parsing, IANA block lookups, and DNS reverse-lookup generation. The library has no runtime dependencies and installs cleanly on Python 3.7 and later.
Typical use is in network automation, infrastructure tooling, and systems administration where you need to work with IP ranges, validate addresses, perform subnet calculations, or look up organizational information tied to IP blocks or MAC vendors. It supports set-based operations (unions, intersections) over address ranges and can parse multiple formats including CIDR, arbitrary ranges, and nmap notation.
Use it for
- Validate and parse user-supplied IP addresses or CIDR blocks in network configuration tools.
- Iterate over all hosts in a subnet or check membership of an IP in a range.
- Perform supernetting or subnetting calculations for network planning.
- Look up IANA IP block ownership or IEEE OUI/IAB information for network diagnostics.
- Generate DNS reverse-lookup zones from IP ranges in DNS management scripts.
