An IPv6 address is a 128-bit unique number that identifies the particular host and destination in a network. The different types of IPv6 addressing are:

Multicast - These addresses are identify a group containing several interfaces. The traffic intended for that group is sent to all of the interfaces of that group.
The following procedures show how to add and remove IPv6 addressess from an interface:
