Java

package com.InterfaceAddress;

import java.net.InterfaceAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.List;

public class InterfaceAddressgetBroadcast {
    public static void main(String[] args) throws SocketException {

        NetworkInterface nif = NetworkInterface.getByIndex(1);
        List<InterfaceAddress> list = nif.getInterfaceAddresses();

        InterfaceAddress interfaceAddress = list.get(0);
