广播 ping 是如何工作的?
你好 有人可以告诉我为什么当我发送广播 ICMP 请求时,只有路由器向我发送 ICMP 回复? 即使我将此 ICMP 请求的 MAC 目的地(原始为 FF:FF:FF:FF:FF:FF)修改为 MAC 特定主机(IP 仍然广播该本地网络...它仍然不向我发送回复。 为什么?

RFC1122 中:“发往 IP 广播或多播地址的 ICMP Echo 请求可能会被静默丢弃”
MS Windows 通常会丢弃广播 ping。检查您的计算机是否确实运行 MS Windows。
From RFC1122: "An ICMP Echo Request destined to an IP broadcast or IP multicast address MAY be silently discarded"
MS Windows usually discard broadcast ping. Check that your computers are really running MS Windows.
