测试多播 - 没有得到正确的结果

之前在这里问过这个问题： https ://networkengineering.stackexchange.com/questions/71813/testing-multicast-problem

但我被指出来了。

我使用这个工具：https ://www.winsocketdotnetworkprogramming.com/winsock2programming/winsock2advancedmulticast9a.html

关闭 Windows 防火墙并关闭 ESET 安全防火墙。

使用：

C:\2>ipconfig

我得到这样的结果：

z:\2>ipconfig
