This read-create RowStatus controls creation and deletion of an IP address pool entry; per the MIB, only 'active' is ever observed on a GET, and only createAndGo and destroy are supported for SET, with entry contents unmodifiable once created except by deleting and recreating. An admin uses it to provision a new dynamic-address pool or remove one no longer needed, understanding that changing an existing pool's range requires deleting and recreating the entry rather than editing in place. Setting rsAddressPoolRowStatus to createAndGo, along with the pool's name, start, and end addresses in the same request, is how an admin provisions a brand-new address pool.
