Multicast allows a single packet to be sent to a group of interested receivers simultaneously. The other classes are: Class A (1.0.0.0–126.255.255.255) for large networks, Class B (128.0.0.0–191.255.255.255) for medium networks, Class C (192.0.0.0–223.255.255.255) for small networks, and Class E (240.0.0.0–255.255.255.255) reserved for experimental use.
