Java 语言实现 IPv6 是否ping通

---

 

1、导入相关的 Java 网络库

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

 

2、定义 ping 方法，传入目标 IPv6 地址

public static boolean ping(String ipv6Address) 
   boolean isPingSuccessful = false;
   try 
      InetAddress inet = InetAddress.getByName(ipv6Address);
      isPingSuccessful = inet.isReachable(5000);
    catch (UnknownHostException e) 
      e.printStackTrace();
    catch (IOException e) 
      e.printStackTrace();
   
   return isPingSuccessful;

 

3、在方法中，使用 InetAddress 类中的 getByName 方法获取目标 IPv6 地址的 InetAddress 实例。

4、使用 InetAddress 实例的 isReachable 方法来判断是否能够连接到目标 IPv6 地址。如果能够连接，则 isReachable 方法返回 true，否则返回 false。

5、使用 try-catch 语句来捕捉 UnknownHostException 和 IOException 异常。

6、最后，返回 ping 是否成功的 boolean 值。

 

示例代码如下：

import java.net.InetAddress;
import java.net.UnknownHostException;
import java.io.IOException;

public class IPv6Ping 
   public static boolean ping(String ipv6Address) 
      boolean isPingSuccessful = false;
      try 
         InetAddress inet = InetAddress.getByName(ipv6Address);
         isPingSuccessful = inet.isReachable(5000);
       catch (UnknownHostException e) 
         e.printStackTrace();
       catch (IOException e) 
         e.printStackTrace();
      
      return isPingSuccessful;
   
   
   public static void main(String[] args) 
      String ipv6Address = "2001:4860:4860::8888";
      boolean isPingSuccessful = ping(ipv6Address);
      if(isPingSuccessful) 
         System.out.println("Ping " + ipv6Address + " successful!");
       else 
         System.out.println("Ping " + ipv6Address + " failed!");
      
   

 

运行结果如下：

Ping 2001:4860:4860::8888 successful!
