Reassigning a Reserved Public IP to a Different Private IP

Move a reserved public IP object from one private IP address to another.

As an example, let's say that you want to move a reserved public IP object from private IP A to private IP B. First, you must ensure that private IP B doesn't have a public IP already assigned to it. Then, you assign the reserved public IP to private IP B. When you do so, it is automatically unassigned from private IP A.

    1. Open the navigation menu and click Compute. Under Compute, click Instances.
    2. Under List scope, select the compartment that contains the instance using the private IP address to which you want to unassign a public IP object.
    3. Under Resources, click Attached VNICs to display the primary VNIC and any secondary VNICs attached to the instance.
    4. Click the VNIC that you're interested in.
    5. Under Resources, click IP Addresses to display the VNIC's primary private IP and any secondary private IPs.
    6. For private IP 2, click the Actions menu (Actions Menu), and then click Edit.
    7. If private IP 2 already has a public IP assigned to it:
      1. In the Public IP Type section, select the radio button for No Public IP.
      2. Click Update.
      3. Again for private IP 2, click the Actions menu (Actions Menu), and then click Edit.
    8. In the Public IP Type section, select the radio button for Reserved Public IP
    9. In the Reserved Public IP list, select the reserved public IP that you want to assign. The IP is moved from the public IP it's assigned to.
    10. Click Update.

  • Use the network public-ip update command and required parameters to reassign a reserved public IP address to a different private IP:

    oci network public-ip update --public-ip-id new_public_IP_OCID --private-ip-id EMPTY_STRING ... [OPTIONS]

    For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

  • Run the UpdatePublicIp operation to reassign a reserved public IP address from one private IP address to another.
