+# Add IPv6 to an IPv4 application in Azure virtual network - Azure CLI
 
 This article shows you how to add IPv6 addresses to an application that is using IPv4 public IP address in an Azure virtual network for a Standard Load Balancer using Azure CLI. The in-place upgrade includes a virtual network and subnet, a Standard Load Balancer with IPv4 + IPV6 frontend configurations, VMs with NICs that have a IPv4 + IPv6 configurations, network security group, and public IPs.
 
-> [!Important]
-> IPv6 support for Azure Virtual Network is currently in public preview. This preview is provided without a service level agreement and is not recommended for production workloads. Certain features may not be supported or may have constrained capabilities. See the [Supplemental Terms of Use for Microsoft Azure Previews](https://azure.microsoft.com/support/legal/preview-supplemental-terms/) for details.

 If you decide to install and use Azure CLI locally instead, this quickstart requires you to use Azure CLI version 2.0.28 or later. To find your installed version, run `az --version`. See [Install Azure CLI](/cli/azure/install-azure-cli) for install or upgrade info.
 
 ## Prerequisites
 
-### Register the service
-
-Before you deploy a dual stack application in Azure, you must configure your subscription for this preview feature using the following Azure CLI:
-
-```azurecli
-az feature register --name AllowIPv6VirtualNetwork --namespace Microsoft.Network
-az feature register --name AllowIPv6CAOnStandardLB --namespace Microsoft.Network
-```
-
-It takes up to 30 minutes for feature registration to complete. You can check your registration status by running the following Azure CLI command:
-
-```azurecli
-az feature show --name AllowIPv6VirtualNetwork --namespace Microsoft.Network
-az feature show --name AllowIPv6CAOnStandardLB --namespace Microsoft.Network
-```
-
-After the registration is complete, run the following command:
-
-```azurecli
-az provider register --namespace Microsoft.Network
-```
-
-### Create a Standard Load Balancer
 This article assumes that you deployed a Standard Load Balancer as described in [Quickstart: Create a Standard Load Balancer - Azure CLI](../load-balancer/quickstart-load-balancer-standard-public-cli.md).
