java代码确认出ip和主机名

总结：：不懂。。。

package com.aa;

import java.net.*;

public class InetAddresTest {

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

		InetAddress ia;
		ia = InetAddress.getByName("www.baidu.com");
		System.out.println("百度网的ip是" + ia.getHostAddress());
		ia = InetAddress.getByName("www.qq.com");
		System.out.println("腾讯的主机地址是：" + ia.getHostAddress());
		ia = InetAddress.getLocalHost();// localhost.指的是本机
		System.out.println("本机ip是：" + ia.getHostAddress());
	}
}

百度网的ip是115.239.210.27
腾讯的主机地址是：101.226.129.158
本机ip是：27.18.219.15
