 ## Argument reference
 Review the argument references that you can specify for your resource. 
 
-- `address_prefix_management` - (Optional, String) Indicates whether a default address prefix should be created automatically `auto` or manually `manual` for each zone in this VPC. Default value is `auto`.
+- `address_prefix_management` - (Optional, Forces new resource, String) Indicates whether a default address prefix should be created automatically `auto` or manually `manual` for each zone in this VPC. Default value is `auto`.
 - `classic_access` - (Optional, Bool) Specify if you want to create a VPC that can connect to classic infrastructure resources. Enter **true** to set up private network connectivity from your VPC to classic infrastructure resources that are created in the same IBM Cloud account, and **false** to disable this access. If you choose to not set up this access, you cannot enable it after the VPC is created. Make sure to review the [prerequisites](https://cloud.ibm.com/docs/vpc-on-classic-network?topic=vpc-on-classic-setting-up-access-to-your-classic-infrastructure-from-vpc#vpc-prerequisites) before you create a VPC with classic infrastructure access. Note that you can enable one VPC for classic infrastructure access per IBM Cloud account only.
 - `default_network_acl`- (Deprecated, String) The ID of the default network ACL.
 - `default_network_acl_name` - (Optional, String) Enter the name of the default network access control list (ACL).
