Mac Vendor Lookup

This library provides an easy way to get vendor information from a MAC address. It contains 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

Update the vendor list

The library contains a list of MAC prefixes obtained at build-time. If you need up-to-date information, you can download a fresh copy of the list directly from IEEE with MacLookup.update_vendors or AsyncMacLookup.update_vendors:

from mac_vendor_lookup import MacLookup

mac = MacLookup()
mac.update_vendors()  # <- This can take a few seconds for the download
    
def find_mac(mac_address):
    print(mac.lookup(mac_address))

Vendor list custom location or path

The library stores and looks for the list of MAC prefixes in a group predefined defaults paths. If a custom directory is required, then override the class variable cache_path of class BaseMacLookup(...) from it default location of: os.path.expanduser('~/.cache/mac-vendors.txt') to your prefered location.

from mac_vendor_lookup import MacLookup, BaseMacLookup

BaseMacLookup.cache_path = "/relative/or/absolute/path/to/the/prefered/storage/location"
mac = MacLookup()
mac.update_vendors()  # <- This can take a few seconds for the download and it will be stored in the new path
    
def find_mac(mac_address):
    print(mac.lookup(mac_address))

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:
