Multicast address: An identifier for a set of interfaces (typically belonging to different nodes), similar to an IPv4 multicast address. A packet sent to a multicast address is delivered to all interfaces identified by that address. There are no broadcast addresses in IPv6. Their function is superseded by multicast addresses.

Anycast address: An identifier for a set of interfaces (typically belonging to different nodes). A packet sent to an anycast address is delivered to one of the interfaces identified by that address (the nearest one, according to the routing protocols’ measure of distance).

The type of an IPv6 address is designated by the first several bits called format prefix. The following table lists the mappings between address types and format prefixes.

3.IPv6 Unicast Address：

IPv6 unicast address is an identifier for a single interface. It consists of a subnet prefix and an interface ID.

Subnet Prefix: This section is allocated by the IANA (The Internet Assigned Numbers Authority), the ISP (Internet Service Provider) or the organizations.

Interface ID: An interface ID is used to identify interfaces on a link. The interface ID must be unique to the link.

There are several ways to form interface IDs. The IPv6 addresses with format prefixes 001 through 111, except for multicast addresses (1111 1111), are all required to have 64-bit interface IDs in EUI-64 format.
