Installation

• Pip (users):

  pip install pyoui
  

• uv (inside your project):

  uv add pyoui
  

• Install from the main branch:

  pip install git+https://github.com/nbdy/pyoui
  

CLI usage

Run:

pyoui --help

Options:

• -o, --outfile: file path for the downloaded IEEE OUI text file
• -d, --debug: enable debug logging
• -p, --prefix: search by MAC prefix (e.g., 00:22:72)
• -org, --organization: search by organization name
• -cc, --country-code: search by 2-letter country code (e.g., US)
• -cn, --country-name: search by country name (e.g., United States)

Examples:

pyoui -p 00:22:72
pyoui -org "national security"
pyoui -cc US

... use by code:

from pyoui import OUI

entries = OUI(debug=True).parse()

print("entries:", entries.size())

e = next(entries.by_organization("national security"))
print("organization", e.organization.__dict__, e.prefix)

e = next(entries.by_prefix("00:22:72"))
print("prefix", e.organization.__dict__, e.prefix)

e = next(entries.by_mac("BC:23:92:42:42:42"))
print("mac", e.organization.__dict__, e.prefix)

e = list(entries.by_country_code("US"))
print("length:", len(e))
print("first item:", e[0].prefix, e[0].organization.__dict__)

ae = list(entries.by_country_name("United States"))
print("by country code length:", len(e), " | by name length:", len(ae))
print("lengths should be equal")

Development

This project uses uv for dependency management and builds.

• Create and sync a virtual environment:

  uv venv
  uv sync
  

• Run tests:

  uv run pytest
  

• Build the package (sdist and wheel):

  uv build
  

• Run the CLI without installing:

  uv run pyoui --help
  

Publishing

Releases are published automatically to PyPI via GitHub Actions using PyPI Trusted Publishing.

• Create a GitHub release (or trigger the workflow manually). Upon a published release, the workflow will:
  • Build the package with uv build.
  • Upload the artifacts to PyPI using pypa/gh-action-pypi-publish with OpenID Connect (OIDC).

To enable trusted publishing, ensure the PyPI project is configured to trust this GitHub repository. See: https://github.com/pypa/gh-action-pypi-publish
