Chapter 2, Planning an IPv6 Addressing Scheme (Overview) introduces the most common IPv6 addressing formats: unicast site address and link-local address. This section includes in-depth explanations of addressing formats that are not covered in detail in Chapter 2, Planning an IPv6 Addressing Scheme (Overview):
If you plan to configure a 6to4 tunnel from a router or host endpoint, you must advertise the 6to4 site prefix in the /etc/inet/ndpd.conf file on the endpoint system. For an introduction and tasks for configuring 6to4 tunnels, refer to Chapter 7, Configuring IP Tunnels.
The next figure shows the parts of a 6to4 site prefix.
Figure 10-1 Parts of a 6to4 Site Prefix
The next figure shows the parts of a subnet prefix for a 6to4 site, such as you would include in the ndpd.conf file.
Figure 10-2 Parts of a 6to4 Subnet Prefix
This table explains the parts of a 6to4 subnet prefix, their respective lengths, and their definitions.

When an IPv6 host receives the 6to4-derived prefix by way of a router advertisement, the host automatically reconfigures a 6to4-derived address on an interface. The address has the following format:
prefix:IPv4-address:subnet-ID:interface-ID/64
The output from the ipadm -a command on a host with a 6to4 interface might resemble the following:
ADDROBJ TYPE STATE ADDR bge0/? addrconf ok 2002:8192:56bb:9258:a00:20ff:fea9:4521/64
This table explains the parts of the 6to4-derived address, their lengths and the information they provide.

The IPv6 multicast address provides a method for distributing identical information or services to a defined group of interfaces, called the multicast group. Typically, the interfaces of the multicast group are on different nodes. An interface can belong to any number of multicast groups. Packets sent to the multicast address go to all members of the multicast group. For example, one use of multicast addresses is for broadcasting information, similar to the capability of the IPv4 broadcast address.
The following table shows the format of the multicast address.
Table 10-1 IPv6 Multicast Address Format

The following is a summary of the contents of each field.
11111111 – Identifies the address as a multicast address.
FLGS – Set of the four flags 0,0,P,T. The first two flags must be zero. The P field has one of the following values:
0 = Multicast address that is not assigned based on the network prefix
1 = Multicast address that is assigned based on the network prefix
If P is set to 1, then T must also be 1.
Reserved - Reserved value of zero.
Plen - Number of bits in the site prefix that identify the subnet, for a multicast address that is assigned based on a site prefix.
Group ID - Identifier for the multicast group, either permanent or dynamic.
For complete details about the multicast format, refer to RFC 3306, "Unicast-Prefix-based IPv6 Multicast Addresses.
Some IPv6 multicast addresses are permanently assigned by the Internet Assigned Numbers Authority (IANA). Some examples are the All Nodes Multicast Addresses and All Routers Multicast Addresses that are required by all IPv6 hosts and IPv6 routers. IPv6 multicast addresses can also be dynamically allocated. For more information about the proper use of multicast addresses and groups, see RFC 3307, "Allocation Guidelines for IPv6 Multicast Addresses".
