当我 ping xxx255 时出现奇怪的响应

当我 ping xxx255 时出现奇怪的响应

这是我的计算机网络配置：

C:\Users\user>ipconfig

Windows IP Configuration

Ethernet adapter Local Area Connection:

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::f56e:2272:8e45:d325%11
   IPv4 Address. . . . . . . . . . . : 10.0.0.81
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 10.0.0.60

问题是为什么当我ping输入 IP 地址时10.0.0.255，会看到以下结果：

C:\Users\User>ping 10.0.0.255

正如您在上面看到的，它没有返回任何内容（因为它10.0.0.255不是有效的 IP 地址，并且是我的网络广播 IP），10.0.0.5而是ping 了10.0.0.154！为什么？

请注意，我检查了路径hosts下的文件Windows\system32\drivers\etc\，如您所见，那里没有重定向：

答案1

因为 Ping 是一种广播兼容服务。收到此类回显请求的计算机将很乐意进行回复。
