Assigning an IP address allocates or reserves the address. You can allocate an address to a host, reserve the address for future use, reserve the address for future DHCP allocation, or assign the address to the network gateway. You can assign addresses individually or in groups, depending on the allocation type.
The different allocation types provide different options and parameters for assigning the address. When setting static or DHCP reserved addresses, you can restrict the address to selected DNS views.
For all address allocations, you can specify a name for the address and associate the address with a device.
To provide better efficiency and flexibility on managing the reverse space, Address Manager supports creating and managing PTR records for unmanaged external hosts through standalone PTR management. This is especially useful for organizations that manage records in reverse DNS zones but do not necessarily manage the corresponding forward zones. You can link IP addresses with existing unmanaged external host records to generate PTR records, or create new unmanaged external host as part of the IPv4 address assigning process.
To assign IPv4 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.
- Under IPv4 Blocks, select the network containing the address or addresses that you want to assign.
Select the check box for one or more addresses in the list.
Tip: To assign an individual IPv4 address, click on the address in the Addresses list.
- Click Action, and then select Assign.
Under General, select an option from the
Allocation Type drop-down menu. Additional fields
appear for each of the allocation types. For more information, refer to IP address allocation types.
- The Applicable Addresses section lists the IP
addresses affected by the assignment you are creating.Attention: When you select more than one address, the Location drop-down menu doesn't appear under the General section. Use Assign Location in the Action menu to assign locations to the assigned IP addresses.
- An Omitted Addresses section appears if addresses you have selected can't be assigned. The Omitted Addresses section lists the addresses from your selection not affected by the assignment you are creating.
- If you have added required user-defined fields for the IPv4 address object types, the user-defined fields appear under General. Enter the value for the user-defined fields to assign IPv4 addresses.
- The Applicable Addresses section lists the IP addresses affected by the assignment you are creating.
When Static or DHCP Reserved are selected as the allocation type,
the DNS section appears. In the
DNS section, select the check box for the view or
views to which the IP address is to be assigned.
Note: If you don't have a DNS view in the configuration, the DNS section doesn't appear.
When Static or DHCP Reserved are selected from the
Allocation Type drop-down list, the
Standalone PTR Records section appears. Under
Standalone PTR Records, set the following
- Views—select a view from the drop-down menu
to specify the DNS view from which you want to select External Host
records or to which you want to add External Host records.
- Existing Unmanaged Host—select this option to link a PTR record to existing external host records in the selected View. Choose an external host record from the drop-down menu and click Add PTR.
- New Unmanaged Host—select this option to create a new external host record in the selected View and link a PTR record to it. Enter the fully qualified domain name and click Add PTR.
- You can add multiple external host records from different views. External host records that are already linked will be displayed.
- To remove an external host record, click Remove beside the external host record.
- Views—select a view from the drop-down menu to specify the DNS view from which you want to select External Host records or to which you want to add External Host records.
Under Additional Information, enter a name for the
address in the IP Address Name field. If you have added
optional user-defined fields for the IPv4 address object types, the user-defined
fields appear under this section.
Note: When assigning multiple IPv4 addresses, if one of the selected IP addresses already has an existing UDF value, the UDF value of that IP address will be applied to all of the selected IP addresses.
In the event that two or more IP addresses have unique UDFs, the UDF of the top-most IP address in the list will be applied to all of the selected IP addresses.
Under IP Address Assignment, set the following
Note: The IP Address Assignment section only appears when assigning a single IP address.
- Duplicate Name Check—select this option to prevent the use of duplicate host names in the network. If this option is set at the higher parent block or network level, by default all child IPv4 addresses will inherit the Duplicate Name Check setting.
- Ping Before Assign—select this option to have Address Manager ping the IP address to check its availability before assigning. If this option is set at the higher parent block or network level, by default all child IPv4 addresses will inherit the Ping Before Assign setting.
Under Device, associate the address with an existing
or new device. The Device section might not be
editable if you don't have the associated access rights.
- Specify Device—select this option if you have already defined devices on the configuration’s Devices tab. Select a device from the drop-down menu.
- New Device—select this option to create a new device. When selected, Name and Type fields appear on the page. In the Name field, enter a descriptive name for the device. From the Type drop-down menu, select a device. Specific devices are listed by the device subtype name followed by the device type name in square brackets.
- Under Change Control, add comments, if required.
- Click Assign.
