java中实现域名解析

import java.net.*;

public class Kkkk {
    public static void main(String args[]) throws Exception {
	InetAddress address = InetAddress.getByName("wxh-PC");// wxh-PC是我的计算机名
	System.out.println(address);
	System.out.println("-----");
	InetAddress address1 = InetAddress.getLocalHost();
	System.out.println(address1);
	
	
	InetAddress[] addresses = InetAddress
		.getAllByName("www.baidu.com");
	System.out.println(addresses.length);
	for (InetAddress addr : addresses) {
	    System.out.println(addr);
	}
    }
}
