This question already has an answer here:

I have a bacnet application which broadcast a message to all devices connected. When i use the address 10.9.x.255, it works and the device is able to get the response but when i use the global broadcast 255.255.255.255, the packet is not reaching the device it has to reach.

What may be the reason for this? I can use the address 10.9.x.255 but i would like to know the reason behind it.

On a different computer it works with global broadcast address but does not work on a specific computer. both computers running on windows 10.

Thanks in Advance
