macaddress
Like ``ipaddress``, but for hardware identifiers such as MAC addresses.
Decision gist · record as of 2026-08-14
Yes, if you need straightforward MAC address parsing and conversion in a stable, dependency-free package. The library is production-ready for its core use case and carries no security vulnerabilities. However, be aware that it is abandoned and will not receive updates or bug fixes; only install if you are comfortable maintaining a fork or accepting the risk of unpatched issues on newer Python versions.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low friction install with no runtime dependencies.
- Last release was 1379 days ago and the repository is marked abandoned, so expect no active maintenance or bug fixes going forward.

What it is and what it does
macaddress is a lightweight library for working with hardware identifiers like MAC addresses, inspired by Python's built-in ipaddress module. It provides classes for common types (EUI48/MAC, EUI64, OUI) and allows you to parse these identifiers from multiple string formats (colon-separated, dash-separated, dot-separated, or raw hex), convert them to and from bytes or integers, and perform equality and ordering comparisons. You can also define custom hardware address types by subclassing the base HWAddress class.
The library has no runtime dependencies and installs cleanly. However, it has been abandoned since its latest release on 2022-11-04 with no commits or updates since 2023-05-26, so it receives no active maintenance. It is marked as Production/Stable in its classifiers, making it suitable for stable, self-contained use cases where you do not expect ongoing support.
Use it for
- Validate and normalize MAC addresses from user input or network device data before storing or processing.
- Convert MAC addresses between common string formats (colon, dash, dot, hex) for compatibility with different tools or protocols.
- Extract the OUI (Organizationally Unique Identifier) from a MAC address to identify the hardware manufacturer.
- Parse and compare hardware identifiers in network monitoring, device inventory, or DHCP/ARP tools.
- Define custom hardware address types (e.g., InfiniBand, CDI) for specialized networking or embedded systems work.
