,v4 = ips.v4 ,v6 = ips.v6 ,ip = ips.ip;

console.log(v4.is('192.168.0.1')); // true
console.log(v6.is('1:2:3:4:5:6:7:8')); // true
console.log(ip.is('1:2:3:4:5:6:7:8')); // true
console.log(ip.contain('abc 192.168.0.1')); // true
console.log(ip.match('abc 1:2:3:4:5:6:7:8')); // ['1:2:3:4:5:6:7:8']

console.log(ip.e('unicorn 192.168.0.1').is()); // false
console.log(ip.e('unicorn 192.168.0.1').contain());  // true
console.log(ip.e('unicorn 192.168.0.1').match());  // [ '192.168.0.1' ]
console.log(ip.e().test('unicorn 192.168.0.1')); // = .contain() -> true
console.log(ip.exact().e().test('unicorn 192.168.0.1')); // = .is() -> fasle
console.log(v6.e()); // /(?:(?:[0-9a-fA-F:]){1,4}(?:(?::(?:[0-9a-fA-F]){1,4}|:)){2,7})+/

var ips = require('relib').ip
,v4 = ips.v4 ,v6 = ips.v6 ,ip = ips.ip;

ip.is('1:2:3:4:5:6:7:8'); // true
ip.is('unicorn 192.168.0.1'); // false
ip.contain('unicorn 192.168.0.1 cake 1:2:3:4:5:6:7:8 rainbow'); // true
ip.match('unicorn 192.168.0.1 cake 1:2:3:4:5:6:7:8 rainbow'); // ['192.168.0.1', '1:2:3:4:5:6:7:8']

v4.is('192.168.0.1'); // true
