How can we distinguish a multi cast address in IP?

A multicast address in IP can be distinguished by its specific address range. For IPv4, multicast addresses range from 224.0.0.0 to 239.255.255.255. In IPv6, multicast addresses start with the prefix "FF00::/8". Additionally, multicast addresses are used to send data to multiple hosts in a single transmission, unlike unicast addresses which target a single host.
