This object manages the lifecycle (create, activate, delete) of an excluded IPv6 address range entry, which defines addresses within a pool the DHCPv6 server should never assign to clients, following standard SNMP RowStatus semantics. An admin uses this to add or remove a reserved sub-range of addresses that must stay out of dynamic assignment, such as ones used by static devices. For example, an admin reserving the first 16 addresses of a pool for infrastructure use would create an excluded range entry covering that sub-range and later use this object to remove it if the reservation is no longer needed.
