public class IntetAddressTest {
	public static void main(String[] args) {
		try {
			InetAddress[] array = InetAddress.getAllByName("MachineName-PC");
			InetAddress address = array[0];
			String ip = address.getHostAddress();
			System.out.println("the ip is = " + ip);
			System.out.println("the InetAddress is = " + array.length);
		} catch (UnknownHostException e) {
