Azure – IP v6 support for VNet is now available in preview

Support for IP v6 is now available in Azure for virtual networks (vNets).

This support allows you for regulatory requirements, better IoT support or better mobility support for your applications.

IP v6 support is available as a dual stack, meaning you can take advantage of it without redeploying your vNets

It is available in preview in all public region at no additional charges – meaning IPv6 resources and bandwidth are charged the same way than for IPv4.

If you want to start using IPv6 support you need to enable the Azure Provider (AllowIPv6VirtualNetwork feature on the Microsoft.Network provider namespace), with PowerShell (or the Cloud Shell) or Cli

  • PowerShell command

Register-AzProviderFeature -FeatureName AllowIPv6VirtualNetwork -ProviderNamespace Microsoft.Network


  • Cli command

az feature register –name AllowIPv6VirtualNetwork –namespace Microsoft.Network


It can take up to 30 minute to get the feature activated; you can check the progress with the PowerShell command (or Cli)

  • PowerShell command

Get-AzProviderFeature -FeatureName AllowIPv6VirtualNetwork -ProviderNamespace Microsoft.Network


  • Cli command

az feature show –name AllowIPv6VirtualNetwork –namespace Microsoft.Network

Once completed, you need to complete the process with

  • PowerShell command

Register-AzResourceProvider -ProviderNamespace Microsoft.Network


  • Cli command

az provider register –namespace Microsoft.Network

Then you are ready to update your existing vNet or deploy new one with IPv6 support.
