2. IPv6 multicast addresses
Figure 4 IPv6 multicast format
Referring to
Figure 4 , the meanings of the fields of an IPv6 multicast address are as follows:
• 0xFF: The most significant 8 bits are 11111111, indicating that this address is an IPv6 multicast
address.
Figure 5 Format of the Flags field
• Flags: Referring to Figure 5 , the following table describes the four bits of the Flags field.
Table 4 Description on the bits of the Flags field
