IP multicast address range

All multicast addresses can be easily recognized because the homologous mode "1110" begins.

224.0.0.0 - 224.0.0.255 well-known multicast address, control channel

224.0.1.0 - 238.255.255.255 Global (Internet wide) multicast address

239.0.0.0 - 239.255.255.255 Local multicast address
