Configuring an Address Allocation Server (AAS)

Releasing, disabling, and re-enabling addresses

You can immediately release an allocated address from its lease if a service has released or expired the address but did not inform the AAS. This will free up the address for use by other services.

WARNING: Do not release an address that is currently in use. This could lead to two or more hosts being configured with the same address at the same time.

If you disable an address, this makes it unavailable for allocation. If the address is currently allocated, it will become unavailable for re-allocation at the conclusion of its current lease. For example, if you remove an address from a pool while the address is currently allocated, disable the address to prevent renewal of the address's lease and avoid disrupting the client currently using the address.

An address that you disable will remain in that state until you subsequently re-enable it.

To release, disable, or enable an address using the Address Allocation Manager:

Select Pools Control.
Select the name of the pool that defines the address whose state you want to change.
Select the address from those listed for the pool. If an address is to be released, its status should be shown as ``ALLOCATED''. If it is to be enabled, its status should be shown as ``DISABLED''.
Select the appropriate action Release, Disable, or Enable.
Click on OK to change the state of the address.
