    • Create one or more IP Address records by selecting allocated IP slots and promoting them to active CMDB Configuration Items. Each new IP Address record uses the host address as its value and is linked to its source allocated IP slot through a Manages relationship.

    Before you begin

    Before you begin:

    • Install all required Modeling your workflow plugins.
    • Role required: core.dc_ops_agent , sn_ni_core.inventory_agent
    • The IP Subnetwork must contain allocated IP records. If it does not, see Allocate IP address slots in a subnetwork .
    • The IP Subnetwork must not have an existing subnet-level IP Address record. If it does, delete that record first, or use the From allocated IPs method on a different subnetwork.

    About this task

    This task is the per-host allocation method. The system creates one IP Address record for each selected allocated IP that is not reserved. Reserved addresses in the selection are skipped silently and reported in the result banner.

    The two IP allocation methods (from allocated IPs and at subnet level) are mutually exclusive on a given subnetwork. Once the first IP Address record is created by either method, the other method is locked for that subnetwork until all IP Address records are deleted. To learn more, see CMDB relationships for IP address records.

    Procedure

    1. Navigate to Workspaces > Network Inventory Workspace or Service Operations Workspace.
    2. Open the IP Subnetwork record.

      (Inventory Number Allocation > IP Network Subnets > select the subnetwork.)

    3. Select the Allocated IP Address tab.
    4. Select the allocated IP records you want to promote to IP Address records:
      1. To select individual records, select the checkbox at the start of each row.
    5. Select Create IP Address Records in the top-right corner of the tab.

      The button is enabled only when one or more allocated IP records are selected.

    6. In the confirmation dialog, review the selection: 
      Create IP Addresses for {N} selected Allocated IP(s)? (Reserved IPs will be skipped)

      The dialog confirms the number of records selected and notes that reserved addresses will be skipped automatically.

    7. Select OK to confirm.

      The system processes the selection and displays a result banner. The banner format depends on the outcome:

    8. Review the created IP Address records on the IP Address tab.

      The tab count updates to reflect the number of new records. Each IP Address record displays the following fields on its detail page:

      Field Description
      Name The address value (matches the IP Address field).
      IP Address The address value.
      IP version IPv4 or IPv6, inherited from the parent subnetwork.
      Owned By Configuration Item Optional reference to the CI that owns this address.
      Netmask Optional.
    9. Review the corresponding allocated IP records on the Allocated IP Address tab.

      The Is Managed flag on each promoted record is now True.

    Result

    Effect on the underlying allocated IP slots For each IP Address record created by this task, the system writes two CMDB relationships: IP Address → Manages → Allocated IP Address — links the new record to the slot it was created from.IP Subnetwork → Contains → IP Address — links the new record to the parent subnetwork. The corresponding allocated IP record’s Is Managed flag is set to True automatically. If you later delete the IP Address record, both relationships are removed and the allocated IP slot’s Is Managed flag flips back to False. The slot itself is preserved and can be promoted again.
