Node.js EUI64

Node module for dealing 64bit IEEE mac addresses.


npm install eui64

var eui64 = require('eui64');
// Pass a hex string seperated by colons. 
var mac = eui64('11:22:33:44:55:66:77:88')
// Pass a hex string seperated by dashes 
var mac3 = eui64('11-22-33-44-55-66-77-88')
// Pass a buffer 
var mac4 = eui64(new Buffer([0x11,0x22,0x33,0x44,0x55,0x66,0x77,0x88]))
// pass a hex string not seperated with or without leading 0x 
var mac5 = eui64('0x1122334455667788')
// or 
var mac6 = eui64('1122334455667788')
// Returns null on invalid input 
eui64('11:22:33:44:55:bogus') // returns null 

Parse the given input and return an object or null on failure

  • input: String separated by colon/dash or not separated or Buffer. (See examples above).

  • options: Object for optional parameters.

          oui : 36, // OUI bit length 24 or 36
          separator : ':' // Separator to be used in toString()

Output current value to string with each octet separated by ':'

Return buffer of current value

Return Number representation of the oui, assumes 36 bit oui.
