Broadcast messages are sent to all stations in the network.
Whereas an unicast message is only sent to one station on the network.
Multicast messages are sent to a group of stations, for example video cameras type. Using multicast allows the building of distribution networks, which are suitable for video monitoring or television transmissions over the Internet, i.e. information with one sender and many receivers.
IPv4 addresses as 255.255.255.255 or 192.168.0.255 are BROADCAST IP addresses.
IPv4 addresses from 188.8.131.52 to 184.108.40.206 are MULTICAST IP addresses.
