A single interface may also have multiple IPv6 addresses of any
type (unicast, anycast, and multicast) or scope.
addresses with a Unicast scope greater than link-scope are not needed for interfaces
that are not used as the origin or destination of any IPv6 packets to
or from non-neighbors.
point This is sometimes convenient for point-to- interfaces. There is one exception to this addressing model: A unicast address or a set of unicast addresses may be
assigned to multiple physical interfaces if the implementation treats
the multiple physical interfaces as one interface when
presenting it to the internet layer.
over This is useful for load-sharing multiple physical interfaces. Hinden
[Page 3] Standards Track RFC 4291
February 2006 IPv6 Addressing Architecture Currently, IPv6 continues the IPv4 model in that a subnet
prefix is associated with one link.
assigned Multiple subnet prefixes may be to the same link. 2.2. Text Representation of Addresses There are three conventional forms for representing IPv6
addresses as text strings: 1. The preferred form is x:x:x:...
