Note
Host Extensions for IP Multicasting [RFC1112] specifies the extensions
required of a host implementation of the Internet Protocol (IP) to
support multicasting.  The multicast addresses are in the range
224.0.0.0 through 239.255.255.255. Address assignments are listed below.

The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive,
is reserved for the use of routing protocols and other low-level
topology discovery or maintenance protocols, such as gateway discovery
and group membership reporting.  Multicast routers should not forward
any multicast datagram with destination addresses in this range,
regardless of its TTL.

(*)  It is only appropriate to use these values in explicitly-

These addresses are listed in the Domain Name Service under MCAST.NET
and 224.IN-ADDR.ARPA.

Note that when used on an Ethernet or IEEE 802 network, the 23
low-order bits of the IP Multicast address are placed in the low-order
23 bits of the Ethernet or IEEE 802 net multicast address
