Note:
Like having reserved the private network segment 10.0.0.0/8 for unicast, IANA has also
reserved the network segments ranging from 239.0.0.0 to 239.255.255.255 for
multicast. These are administratively scoped addresses. With the administratively
scoped addresses, you can define the range of multicast domains flexibly to isolate IP
addresses between different multicast domains, so that the same multicast address
can be used in different multicast domains without causing collisions.
II. Ethernet multicast MAC address
When a unicast IP packet is transported in an Ethernet network, the destination MAC
address is the MAC address of the receiver. When a multicast packet is transported in
an Ethernet network, a multicast MAC address is used as the destination address
because the destination is a group with an uncertain number of members.
