The resulting address is Prefix length is stated in classless inter-domain routing (CIDR) notation.
CIDR notation is a slash at the end of the address that is followed by the prefix length in bits.
For information on CIDR format IP addresses, refer to Designing Your CIDR IPv4 Addressing Scheme.
The site prefix of an IPv6 address occupies up to 48 of the leftmost bits of the IPv6 address.
The prefix describes the public topology that is usually allocated to your site by an ISP or Regional Internet Registry (RIR).
The next field is the 16-bit subnet ID, which you (or another administrator) allocate for your site.You assign a subnet ID as part of IPv6 network configuration.The subnet prefix defines the site topology to a router by specifying the specific link to which the subnet has been assigned.The link-local unicast address can be used only on the local network link.Link-local addresses are not valid nor recognized outside the enterprise.The following example shows the format of the link-local address.When you enable IPv6 during Solaris installation, the lowest numbered interface on the local machine is configured with a link-local address.The interface ID identifies an interface of a particular node. IPv6 hosts can use the Neighbor Discovery protocol to automatically generate their own interface IDs.Neighbor Discovery automatically generates the interface ID, based on the MAC or EUI-64 address of the host's interface.IPv6 subnets are conceptually the same as IPv4 subnets, in that each subnet is usually associated with a single hardware link.However, IPv6 subnet IDs are expressed in hexadecimal notation, rather than in dotted decimal notation.
