No ping to a multicast address from Windows
提问by ComPTALot
On my computer, when I try to ping to a multicast address, none of them return a response.
在我的计算机上，当我尝试 ping 到多播地址时，它们都没有返回响应。
On the other hand, there is a Unix server I know that does have ping to these addresses.
另一方面，我知道有一台 Unix 服务器可以 ping 这些地址。
Is there a way to add a route from my computer to this one, so that I can use these addresses?
有没有办法添加从我的计算机到这个的路由，以便我可以使用这些地址？

No, ICMP is not typically used with multicast because it is a prime source for DoS amplification. Similarly multicast doesn't tend to be that useful as you need multicast enabled and configured routers to cross LAN segments.
不，ICMP 通常不用于多播，因为它是 DoS 放大的主要来源。类似地，多播往往没有那么有用，因为您需要启用多播并配置路由器以跨 LAN 网段。
