Dual Stack IPv4/IPv6 Connectivity allows you to bring your private IPv6 space into Azure and enables connectivity over IPv6 within your Virtual Networks. This enables you to address IPv4 depletion, meet regulatory requirements and expand into the growing mobile and IoT markets with your Azure-based applications.

IPv6 is used by:

Government or customers in highly regulated industries

Internet-of-Things applications that leverage the enormous number of IPv6 addresses available

Customers who want native (not translated) connectivity from their Azure applications to IPv6 mobile devices

Customers who deploy service instances in Azure with dedicated per-customer connectivity

Customers moving to the cloud (or hybrid) struggling with exhaustion of their IPv4 space and inability/expense of acquiring more IPv4.

Dual Stack VNET also:

Builds on long-established Azure VM-to-Internet IPv6 connectivity

Enables fully IPv6 architectures to be hosted in Azure with IPv6 connectivity between VMs in a VNET, using IPv6 Network Security Group rules, IPv6 User-defined routes and load balancing across VMs

Allows Azure customers to define their own IPv6 address space to meet the needs of their applications or customers

Provides “Dual Stack Upgrade-in-place” - where customers can add IPv6 connectivity to their existing applications without re-deploying

Provides maximum service deployment flexibility - a single service instance can connect with both IPv4 and IPv6-capable Internet clients

Dual Stack connectivity will preview globally in all Azure Public cloud regions, so you can try it out in a region that is convenient for you.
