If you no longer require an IP Address Pool or Sub-Pool, you can release the address
space.
Note: The IP Address Pool or Sub-Pool must be empty before it can be released.
Empty IP Address Pools and Sub-Pools do not contain any Sub-Pools and do not have
any assigned IP addresses.

- In the menu, select .
- In the Network Settings page, select the IP Address Pools tab.

- Click Yes to confirm that you would like to release the IP Address Pool or Sub-Pool.
Verifying that the IP Address Pool has been removed from Address Manager
