A single interface may be assigned multiple addresses of any type (unicast, anycast, multicast).
Every IPv6-enabled interface must contain at least one loopback and one link-local address.
Optionally, every interface can have multiple unique local and global addresses. IPv6 host addresses can be assigned in multiple ways:

Static configuration -

Stateless autoconfiguration -

DHCPv6 -
When IPv6 is used over Ethernet networks, the Ethernet MAC address can be used to generate the 64-bit interface ID for the host. This is called the EUI-64 address. Since MAC addresses use 48 bits, additional bits must be inserted to fill the 64 bits required.
