The first 4BIT of the IP multicast address is a fixed 1110, corresponding to the high 25BIT of the multicast MAC address. Only 23BIT of the last 28BIT of the IP multicast address is mapped to the MAC address, so the address information of 5BIT is lost. The direct result is that there are 32 IP multicast addresses mapped to the same MAC address.
