* IP地址转化为整数 (js实现)

function ip2int(ip) {
    return ip.split('.').map(function(s) {
        return s.split('').reduce(function(a, c, i) {
            return (a = 10*a + c.charCodeAt(0)-48)
        }, 0);
    }).reduce(function(a, c, i, array) {
        return (a |= c << (array.length-i-1)*8)
    }, 0);
}

var ip_int = ip2int("47.96.133.100");
console.log(ip_int);

Output:
