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|
|DHCP Reserved||Yes||Yes - only when no host name assigned||n/a||no|
- 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.
To change the state of IP addresses:
- Select the IP Space tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
- From the configuration drop-down menu, select a configuration.
- Select a network and IPv4 block to list the IP ranges.
- Select the check box for one or more addresses in the list.
- Click Action, and then select Change IP state.
Under General, select an option from the IP
State drop-down menu. Additional fields appear for each of the
allocation types. For more information, refer to IP address allocation types.
Note: The Applicable Addresses section will display only those IP addresses which are allowed to change to state that you have selected in the General section. Any IP addresses that do not meet criteria for allowable state changes are listed in the Omitted Addresses section.
- Under Change Control, add comments, if required.
- Click Update.
