JAVA
java.InetAddress类表示互联网协议 (IP) 地址。
有两个子类:Inet4Address, Inet6Address
通过 InetAddress可以方便获取一个域名下的IP,也可以获取一个IP的主机名。
下面是例子,通过程序查看bitscn主机的IP信息,bitscn是不让ping的。
代码:
import java.io.IOException; import java.InetAddress; public class TestInetAddress { public static void main(String[] args) throws IOException { test(); } public static void test() throws IOException { //获取本机的IP地址 InetAddress address1 = InetAddress.getLocalHost(); System.out.println(address1.getHostAddress()); System.out.println(address1.toString()); System.out.println("---------------"); //获取51cot的IP地址 InetAddress address2 = InetAddress.getByName("www.bitscn"); System.out.println("getHostAddress:\t" + address2.getHostAddress()); System.out.println("getHostName:\t" + address2.getHostName()); System.out.println("---------------"); //获取我博客的IP地址 InetAddress address3 = InetAddress.getByName("lavasoft.blog.bitscn"); System.out.println("getHostAddress:\t" + address3.getHostAddress()); System.out.println("getHostName:\t" + address3.getHostName()); //直接用ip地址构建 System.out.println(InetAddress.getByName("211.103.156.224")); System.out.println("---------------"); //获取www.google域名下所有的IP地址 // InetAddress[] address4 = InetAddress.getAllByName("www.microsoft"); InetAddress[] address4 = InetAddress.getAllByName("www.google"); for (InetAddress address : address4) { // System.out.println(address.getHostAddress()); System.out.println(address); } InetAddress address5 = InetAddress.getByName("211.103.156.229"); System.out.println(address5.isReachable(10)); } } |
运行输出结果:
192.168.1.2 Process finished with exit code 0 |
