package com.zzl.thread;

import java.net.InetAddress;
import java.net.UnknownHostException;





public class NetDemo {

	public static void main(String[] args) {
		
		
		try {
			//获取本机的ip地址和计算机名
			InetAddress ia = InetAddress.getLocalHost();
			String name = ia.getHostName();
			String address = ia.getHostAddress();
			System.out.println("name==="+name);
			System.out.println("address==="+address);
		} catch (UnknownHostException e) {
			e.printStackTrace();
		}
		
		try {
			//获取百度的主机地址和主机名
			InetAddress ia = InetAddress.getByName("www.baidu.com");
			String name = ia.getHostName();
			String address = ia.getHostAddress();
			System.out.println("百度name=="+name);
			System.out.println("百度address=="+address);
		} catch (UnknownHostException e) {
			e.printStackTrace();
		}
	}

}

运行结果：

name===admin-PC
address===192.168.0.124
百度name==www.baidu.com
百度address==61.135.169.125
