random-ip

generate random ip(v4 or v6) addresses

why

just playing around with ipv6 and wanted to be able to generate addresses in arbitrary ranges

how

* depends on @indutny's node-ip to parse ip addresses
* uses Math.random() to randomly twiddle bits within in the CIDR range you specify

example

``javascript
var randomip = require('random-ip');

// ipv6
randomip('::', 64) // 0:0:0:0:f46c:cde1:a409:d38f
randomip('::', 64, 80) // 0:0:0:0:9eba:0:0:0
randomip('2001:470:e01::', 48, 64) // 2001:470:e01:da2f:0:0:0:0

// ipv4
randomip('0.0.0.0', 24) // 0.0.0.136
randomip('0.0.0.0', 16, 24) // 0.0.68.0
randomip('192.168.2.0', 24) // 192.168.2.240
