java.net.InetAddress简单使用

import java.io.IOException;import java.net.InetAddress;import java.net.UnknownHostException;public class Test1 {public static void main(String[] args) throws IOException {InetAddress ip = InetAddress.getLocalHost();System.out.println(ip);//hqq-PC/10.10.11.128System.out.println(ip.getHostName());//hqq-PCSystem.out.println(ip.getHostAddress());//10.10.11.128ip = InetAddress.getByName("www.inspur.com");System.out.println(ip);//www.inspur.com/218.57.146.152System.out.println(ip.getHostName());//www.inspur.comSystem.out.println(ip.getHostAddress());//218.57.146.152int timeout = 5000;//单位毫秒System.out.println(ip.isReachable(timeout));//是否可以ping通，返回true或false}}
