You can change the status (DHCP reserved, Static and Reserved) of one or more IP addresses at the same time.

The following IP address state changes are permitted:

From/To Static Reserved DHCP Reserved DHCP Allocated
Static n/a Yes - only when no host name assigned Yes no
Reserved Yes n/a Yes no
DHCP Reserved Yes Yes - only when no host name assigned n/a no
DHCP Allocated no no yes n/a
Note:
  • MAC addresses are mandatory when selecting DHCP reserved. Each MAC address must be unique and not in use by any other IP address within the same network.
  • You are only permitted to change the status of multiple IP addresses if your workflow change request permission is not set to Recommended as described in Workflow change requests. If your workflow permission is set to recommended, you can only change one IP address per transaction.
  • If you are attempting to change the state of an IP address which is part of a pending workflow transaction, you will not be permitted to change the state until the pending transaction is complete.
  • If you attempt to change the status of an IP address to reserved and the IP address has a host name associated with it, you will not be able to change the state of the IP address. It will be moved to the omitted list, per the address type definitions in Address types.
  • In a Windows environment the Windows servers must be read-write to effect this kind of change. If the Windows servers are read-only, the status changed can not be implemented.
Important: If your network contains fewer than 4 addresses (that is, /31 or /32 networks), you cannot change the IP address state to DHCP Reserved. In the Change IP State page, DHCP Reserved is unavailable.
