This MIB object identifies the scope of the IPv6 address. This can take the following values based on whether the address is unicast/anycast or multicast. 0 reserved 1 Interface-Local scope 2 Link-Local scope 3 reserved 4 Admin-Local scope 5 Site-Local scope 6 (unassigned) 7 (unassigned) 8 Organization-Local scope 9 (unassigned) 10 (unassigned) 11 (unassigned) 12 (unassigned) 13 (unassigned) 14 Global scope 15 reserved Link-local and global scopes are applicable for unicast/anycast addresses. The following are valid multicast scopes - Interface-Local scope spans only a single interface on a node and is useful only for loopback transmission of multicast. Link-Local is used for uniquely identifying interfaces within a single link. Admin-Local scope is the smallest scope that must be administratively configured, i.e., not automatically derived from physical connectivity or other, non-multicast-related configuration. Site-Local scope is intended to span a single site. Organization-Local scope is intended to span multiple sites belonging to a single organization. Global scope is used for uniquely identifying interfaces anywhere in the Internet scopes labeled (unassigned) are available for administrators to define additional multicast regions.
