It is often useful in documentation, IETF documents, etc., to provide
examples containing IP multicast addresses. For documentation where
examples of general purpose multicast addresses are needed, one
should use multicast addresses that never will be assigned or in
actual use. There is a risk that addresses used in examples may
accidentally be used. It is then important that the same addresses
are not used by other multicast applications or services. It may
also be beneficial to filter out such addresses from multicast
signalling and multicast data sent to such addresses.
For unicast there are both IPv4 and IPv6 addresses reserved for this
purpose, see [RFC5737] and [RFC3849] respectively. This document
reserves multicast addresses for this purpose.
There are also some multicast addresses that are derived from AS
numbers or unicast addresses. For examples where such addresses are
desired, one should derive them from the AS numbers and unicast
addresses reserved for documentation purposes. This document also
discusses the use of these.
