You may want to deprovision a pool CIDR to free up IP address space, simplify IP address
management, prepare for network changes, or meet compliance requirements. Deprovisioning a pool CIDR allows for better control and optimization of your IP address
allocations within IPAM, while ensuring unused IP space is reclaimed and made available for
future use. You can't deprovision the CIDR if there are allocations in the pool. To remove allocations,
see Release an allocation.
Follow the steps in this section to deprovision CIDRs from an IPAM pool.
When you deprovision all pool CIDRs, the pool can no longer be used for allocations.
You must first provision a new CIDR to the pool before you can use the pool for allocations.
