I'm kinda new to networking. I have a small question, how can I determine what type of casting (unicast, multicast or broadcast) is it based on IPv4 address. For example:

*Broadcast addresses are more complicated. There is the limited broadcast address ( that works on all networks, but there is also a network broadcast address that is the last address in a network.
