Figure 4 IPv6 multicast format
The following describes the fields of an IPv6 multicast address:
0xFF—The most significant eight bits are 1 1 1 1 1 1 1 1, which means that this address is an IPv6
multicast address.
Flags—The Flags field contains four bits.

•
When set to 0, it means that this address is an IPv6
multicast address without an embedded RP address.
•
When set to 1, it means that this address is an IPv6
multicast address with an embedded RP address. (The P
and T bits must also be set to 1.)
•
When set to 0, it means that this address is an IPv6
multicast address not based on a unicast prefix.
•
When set to 1, it means that this address is an IPv6
multicast address based on a unicast prefix. (The T bit must
also be set to 1.)
•
When set to 0, it means that this address is an IPv6
multicast address permanently-assigned by IANA.
•
When set to 1, it means that this address is a transient, or
