如何在jQuery中使用对象IP地址和掩码IP地址计算网络和广播？

Question

对象IP地址= 192.168.0.101

掩码IP地址= 255.255.255.0

网络=？

广播=？

Answer 1

var network = calculateNetworkIP("192.168.0.101", "255.255.255.0");

var broadcast = calculateBroadcastIP("192.168.0.101", "255.255.255.0");

        binaryNetwork.push(bitwiseAND(binaryIP[j], maskBinaryIP[j]));
    }

    var NetworkIPArr = convertBinaryIPToDecIP(binaryNetwork);

    var NetworkIPStr = "";
    for (var k = 0; k < NetworkIPArr.length; k++) {
