Question

对象IP地址= 192.168.0.101

掩码IP地址= 255.255.255.0

network =？

broadcast =？

Answer 1

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

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

    var NetworkIPArr = convertBinaryIPToDecIP(binaryNetwork);

    var NetworkIPStr = "";
