import java.net.*;

class IPDemo

{
	public static void main(String[] args) throws Exception
	{
		//获取本地主机IP
		//InetAddress i = InetAddress.getLocalHost();
		//System.out.println(i.toString());
		
		//可以用于域名解析
		InetAddress[] ia = InetAddress.getAllByName("www.baidu.com");
		for(int i = 0;i < ia.length;i++)
		{
			System.out.println(ia[i]);
		}
		
		
		
		//用Inet4Address中的方法获取本地主机IP
		Inet4Address ia4= (Inet4Address)InetAddress.getLocalHost();
		System.out.println(ia4.toString());
