import java.net.*;



public class NetDemo {



    public static void main(String[] args) throws Exception{



        String str = "172.20.223.120";

        String[] ipStr = str.split("\\.");

        byte[] ipBuf = new byte[4];

        for(int i = 0; i < 4; i++){

            ipBuf[i] = (byte)(Integer.parseInt(ipStr[i])&0xff);

        }



        InetAddress ia = InetAddress.getByAddress("hao.wen",ipBuf);

        System.out.println(ia);
