 The following commands can be used in Azure CLI and Azure PowerShell to deprovision and remove the range from Microsoft. The deprovisioning operation is asynchronous. You can use the view commands to retrieve the status. The **CommissionedState** field will initially show the prefix as **Deprovisioning**, followed by **Deprovisioned** as it transitions to the earlier state. When the range is in the **Deprovisioned** state, it can be deleted by using the commands to remove.
