  • Assign an existing reserved public IP address object to a private IP address object.

  • Create and assign a reserved public IP address object in one step.

  • Move a reserved public IP address object to a different private IP address object.

  • Unassign a reserved public IP address object from a private IP address object.

  • Change the display name or tags for a public IP address object.

Avoid entering confidential information in names.

    2. At the top of the page, select the compartment that contains the instance for which you want to update a public IP address.

    3. Click the name of the instance.

      The instance details page is displayed.

    4. Under Resources, click Attached VNICs.

      Click the name of the VNIC for which you want to assign a public IP address.

      The primary private IP address and any secondary private IP addresses, and any attached public IP addresses, are shown in the table.
