java 获得本地IP和远程服务器IP

import java.io.IOException;import java.net.InetAddress;import java.net.UnknownHostException;/*获取IP地址*/public class CatchIp {private InetAddress LocalIP = null;private InetAddress ServerIP = null;public static void main(String[] args) {CatchIp mytest;mytest = new CatchIp();System.out.println("LocalHost IP is:"+mytest.catchLocalIP());System.out.println("Server IP is:"+mytest.catchServerIP());}//取得本机IP地址public InetAddress catchLocalIP(){try {LocalIP = InetAddress.getLocalHost();} catch (UnknownHostException e) {}return LocalIP;}//取得服务器网络地址public InetAddress catchServerIP(){try {ServerIP = InetAddress.getByName("www.sina.com.cn");//取得www.sina.com.cn的IP地址} catch (UnknownHostException e) {System.out.println(e.getMessage());}return ServerIP;}}
