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:

  1. Select the IPAM tab in the sidebar, then select IPv4 blocks.
  2. Navigate to the IPv4 network that contains the IPv4 addresses you want to assign by selecting the network's range in the IPv4 blocks and networks table, or by selecting the network in the IPAM tree view panel.
  3. Select the check box for one or more IPv4 addresses in the IPv4 addresses table, then select Actions > Assign addresses
    Tip: To assign an individual IPv4 address, select the row containing the IP address in the IPv4 addresses table.
  4. Under General, set the following parameters:
    1. Allocation type—select the state to assign the IPv4 address from the following options. For more information, refer to IP address allocation types.
      • Static—select this option to assign the IP address to a particular host.
      • DHCP reserved—select this allocation type to reserve the address for the DHCP service. When you select this option, the following additional fields appear:
      • Reserved—select this option to designate the IP address as reserved and unavailable for assignment.
    2. MAC address—enter the MAC address for the IP address in the format nnnnnnnnnnnn, nn-nn-nn-nn-nn-nn, or nn:nn:nn:nn:nn:nn, where nn is a hexadecimal value from 00 to FF.
    3. Hostname (Static and DHCP reserved only) —select from the following options:
      • Same as zone—select this option to give the host the same name as the zone.
      • Specify name—enter the name for the host record assignment.
    4. Reverse record (Static and DHCP reserved only)—select the checkbox to create a reverse record for the host.
    5. Assign to MAC pool (DHCP reserved only)—select the checkbox, then select a MAC pool from the drop-down menu to link the MAC address to a pool. Users will only see the MAC pool to which they have view access rights.
    6. Template (DHCP reserved only)—enter the name of an IPv4 template to assign a template to the IP address.
    7. Location—select a location from the drop-down menu to associate the IP address to a location.
    8. IP address name—enter a descriptive name for the IP address.
  5. The Applicable addresses tab lists the IP addresses that will be affected by the assignment action.
  6. When Static or DHCP reserved are selected as the allocation type, the DNS tab appears. In the DNS section, enter the view or views to which the IP address is to be assigned.
  7. When Static or DHCP reserved are selected as the allocation type, the PTR records tab appears. Under PTR records, set the following options:
    • View—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.
      • Use existing unmanaged host—select this option to link a PTR record to existing external host records in the selected view. Enter a the name of an external host record in the Select unmanaged host field and select Add PTR record.
      • Create a 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 in the Unmanaged host name field and select Add PTR record.
      • 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, select the Remove button beside the external host record.
  8. Under Assignment options, set the following parameters:
    • 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 assignment—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 assignment setting.
  9. In the Device section, associate the address with a new or existing device. The Device section may not be editable if you don't have the associated access rights.
    • Select existing device—select this option if you have already defined devices on the Devices page. Enter the name of the device in the Device field.
    • New device—select this option to create a new device. In the Device name field, enter a descriptive name for the device.
  10. In the Change control section, add comments if required.
  11. Select Assign.
