IPv6 in Azure VNET is currently previewing globally- in ALL Azure Public cloud regions.
Announcement (Service Update): https://azure.microsoft.com/en-us/updates/public-preview-microsoft-adds-full-ipv6-support-for-azure-vnets/
Links to Documentation & Samples
Full documentation including sample scripts is available here: https://aka.ms/IPv6ForAzureVNETdoc
A sample JSON template is posted in the quickstart repository: https://azure.microsoft.com/en-us/resources/templates/ipv6-in-vnet/
- as Kyle Williams noted, the ability to add IPv6 to VPNs, particularly multisite VPNs
- related to above, the ability to bring your own IPv6 PI space to a VM network (which, generally speaking, probably means NAT66 toward the internet, but whatever)
- the ability to associate an IPv6 address to a VM without a load-balancer
- related to the last, the ability for VMs to talk to one another over IPv6
- a less convoluted path to creating VM assets with IPv6 addresses (the walkthrough I saw for the load-balanced solution was...painful, IMO)
Apparently Microsoft "started" their efforts two months after this was first suggested, but there's no indication what progress has actually occurred: http://feedback.azure.com/forums/217313-networking-dns-traffic-manager-vpn-vnet/suggestions/4992369-support-ipv6-throughout-the-azure-platform
Speaking with both my Microsoft enterprise customer and IPv6 expert hats on, IPv6 support in Azure is long overdue.
We have Public IP Prefix – you can reserve a block of IPv4 addresses.
