What is rlDhcpSrvDynamicFreeNumOfAddr?
This read-only Unsigned32 reports the number of free addresses remaining in this dynamic pool's address space. An admin monitors this to catch pool exhaustion before it causes new clients to fail to obtain a lease. For example, watching this value drop toward zero during a busy office day would prompt the admin to expand the pool's address range.
