Mac Vendor Lookup

This library provides an easy way to get vendor information from a MAC address. It downloads a local copy of the IEEE's OUI prefix list. It has an asynchronous interface using Python 3's asyncio as well as a regular synchronous interface for old-school usage.

Installation

pip install mac-vendor-lookup

Basic Usage

from mac_vendor_lookup import MacLookup

print(MacLookup().lookup("00:80:41:12:FE"))

Output:

VEB KOMBINAT ROBOTRON

Pre-load the vendor list

The list of MAC vendors is currently about 4MB large. By default a lazy-loading mechanism is used, that loads the list when it's needed. If it is clear that the list is needed and a wait time during the query is not desired, the list can also be loaded when the program is started:

from mac_vendor_lookup import MacLookup

mac = MacLookup()
mac.load_vendors()  # <- This can take a few seconds for the first download
    
def find_mac(mac_address):
    print(mac.lookup(mac_address))  # <- this will only take a few µs!

Async Interface

There is also an asynchronous interface available:

from mac_vendor_lookup import AsyncMacLookup

async def main():
    mac = AsyncMacLookup()
    print(await mac.lookup("98:ED:5C:FF:EE:01"))

Output:

Tesla Motors, Inc

Command line interface

This library provides a rudimentary command line interface:
