mac-vendor-lookup
Find the vendor for a given MAC address
Decision gist · record as of 2026-08-14
Yes, if you need MAC-to-vendor resolution. The package is stable, permissively licensed, has minimal dependencies, and supports both sync and async workflows. The aging maintenance status (257 days since last release) is a minor concern but not a blocker—the core functionality is straightforward and unlikely to require frequent updates. No known vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with only two runtime dependencies (aiofiles, aiohttp).
- Last release was recent, and the repository remains active with 86 stars, though maintenance status is aging—no updates in 257 days.

What it is and what it does
mac-vendor-lookup is a Python library that maps MAC addresses to their vendor names using a local copy of the IEEE's OUI (Organizationally Unique Identifier) prefix list. It provides both a synchronous interface for straightforward lookups and an asynchronous interface built on asyncio for non-blocking operations. The library ships with a pre-built vendor list and can optionally download a fresh copy from IEEE when needed.
The package is designed for network administration, device discovery, and hardware identification tasks where you need to determine which manufacturer produced a network interface given its MAC address. It includes a command-line tool for quick lookups and allows customization of the vendor list cache location.
Use it for
- Identify network device manufacturers in network scanning or inventory tools
- Resolve MAC addresses to vendor names in DHCP or ARP monitoring applications
- Build device discovery systems that classify hardware by manufacturer
- Enrich network logs or packet captures with vendor information
- Implement async MAC lookups in high-throughput network analysis pipelines
