使用程序简单查询IP地址

查询IP

package Demo01;

import java.net.InetAddress;

//测试IP
    public class TestInetAddress {
        public static void main(String[] args) {
            try {
                //查询本机地址
                InetAddress  InetAddress1 = InetAddress.getByName("127.0.0.1");
                System.out.println( InetAddress1);  ///127.0.0.1
                InetAddress  InetAddress3 = InetAddress.getByName("localhost");
                System.out.println( InetAddress3);  //localhost/127.0.0.1
                InetAddress  InetAddress4 = InetAddress.getLocalHost();
                System.out.println( InetAddress4);  //DESKTOP-PQLGR9D/192.168.177.1

                //查询网站ip地址
                InetAddress  InetAddress2 = InetAddress.getByName("www.baidu.com");
                System.out.println( InetAddress2);  //www.baidu.com/183.232.231.174

                System.out.println("=============================================");
                
                //常用方法
                System.out.println(InetAddress2.getAddress());  //[B@131245a
                System.out.println(InetAddress2.getCanonicalHostName());//规范的名字    183.232.231.174
                System.out.println(InetAddress2.getHostAddress());//ip   183.232.231.174
                System.out.println(InetAddress2.getHostName());//域名，或者本机电脑的名字  www.baidu.com
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
