推荐答案

以下内容使用Amazon Web服务并为我工作.

The following uses Amazon web services and works for me.

import java.net.*;
import java.io.*;
public class IPTest{    
    public static void main(String args[]) throws Exception{
            URL whatismyip = new URL("http://checkip.amazonaws.com/");
            BufferedReader in = new BufferedReader(new InputStreamReader(
                            whatismyip.openStream()));

            String ip = in.readLine(); //you get the IP as a String
            System.out.println("My IP address:"+ip);
    }
}
