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);
}
}
