IEEE OUI Database

oui-data provides the IEEE Organizationally Unique Identifier (OUI) database as a static JSON file, enabling programmatic access to MAC address vendor information. The current stable version is 1.1.571. This package primarily serves as a data source, with updates typically tied to upstream IEEE OUI registry changes and dependency bumps, implying an as-needed release cadence rather than a fixed schedule. Its key differentiator is simplicity and direct JSON export, making it easy to consume in environments that support JSON module imports or require/import raw JSON. It eschews any processing logic or API, focusing solely on delivering the raw, structured OUI data.
