Multicast Address

A multicast address is associated with a group of interested receivers. According to RFC
3171, addresses 224.0.0.0 to 239.255.255.255, the former Class D addresses, are
designated as multicast addresses in IPv4.
The IANA owns the OUI MAC address 01:00:5e, therefore multicast packets are delivered
by using the Ethernet MAC address range 01:00:5e:00:00:00 - 01:00:5e:7f:ff:ff. This is 23
bits of available address space.
