ipaddr
Google's IP address manipulation library
Decision gist · record as of 2026-08-14
No. Do not install this package for new projects—use the standard library ipaddress module instead. For legacy Python 2 codebases already using ipaddr, keep it only as long as necessary during migration. The package is abandoned, receives no maintenance or security updates, and its functionality is fully available in modern Python's standard library.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Package is abandoned and superseded by the standard library ipaddress module; use that instead for new projects.
- Installation friction is high due to source-only distribution.
- More importantly, the package is abandoned—last release was 2017-09-15, repository is archived, and no commits since 2023-04-09.

What it is and what it does
ipaddr is a library for working with IP addresses, both IPv4 and IPv6, providing parsing, validation, and manipulation utilities. It was originally developed by Google but has been superseded by the ipaddress module in Python 3's standard library and its Python 2 backport.
The package is no longer maintained—its repository is archived, the last release was in 2017-09-15, and no commits have been made since 2023-04-09. For any new code, you should use the standard library ipaddress module instead. This package exists primarily for legacy Python 2 projects that cannot migrate; it carries no known security vulnerabilities but receives no updates or support.
Use it for
- Maintaining legacy Python 2 codebases that depend on ipaddr and cannot yet migrate to the standard library.
- Parsing and validating IP addresses in older applications where upgrading dependencies is not feasible.
- Working with network ranges in Python 2 environments without access to ipaddress.
- Checking whether an IP address belongs to a particular network in legacy systems.
