mac-lookup

A node module to fetch, parse, and lookup entries from the IEEE's OUI database. Adapted from node-ieee-oui-lookup.

Install

npm install mac-lookup

Usage

Loading using Config:

// Config is optional
var config = {
  csv: './oui.csv'
}

var mac = require('mac-lookup')(config);

// if defining a custom config, make sure to rebuild at least once to generate sqlite3 db
mac.rebuild();
mac.load(done => {
  done();
});

// ...

Loading Using Promises:

'use strict';

const {promisify} = require('util');
const macLookup   = require('mac-lookup');

const asyncMacLookupLoad = promisify(macLookup.load).bind(macLookup);

(async function () {
    await asyncMacLookupLoad();
    const name = macLookup.lookup('000000')
    console.log(name);
}());

To lookup a MAC prefix:

mac.lookup('00:00:00', function (err, name) {
  if (err) throw err;
  // name will be null if not found.
  console.log('00:00:00 -> ' + name);
});

You can also look up the full mac address with or without full dash, dot, or colon notation:

mac.lookup('0000.0000.0000',function (err, name) {
  if (err) throw err;
  // name will be null if not found.
  console.log('0000.0000.0000 -> ' + name);
});)

If you think the internal DB is outdated, you can rebuild it from the latest file with:

mac.rebuild(function (err) {
  if (err) throw err;
  console.log('rebuild completed');
});

Iterate thru the entire db

function done() { console.log('done'); }

mac.each(function (err, result) {
  console.log('oui',  result.oui);
  console.log('name', result.name);
}, done);
