//IP转成整型function ip2int(ip){    var num = 0;    ip = ip.split(".");    num = Number(ip[0]) * 256 * 256 * 256 + Number(ip[1]) * 256 * 256 + Number(ip[2]) * 256 + Number(ip[3]);    num = num >>> 0;    return num;}//整型解析为IP地址function int2iP(num){    var str;    var tt = new Array();    tt[0] = (num >>> 24) >>> 0;    tt[1] = ((num << 8) >>> 24) >>> 0;    tt[2] = (num << 16) >>> 24;    tt[3] = (num << 24) >>> 24;    str = String(tt[0]) + "." + String(tt[1]) + "." + String(tt[2]) + "." + String(tt[3]);    return str;}
