JS library for dealing with IEEE-defined 64bit extended unique identifier.
npm install eui64Node module for dealing 64bit IEEE mac addresses.

npm install eui64
``js
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.
