Azure IP strategy

I am looking to create an IP strategy for a hybrid environment (VMware on prem and Azure public integrated). I am wondering if anyone has best practice on best practices for IP strategy and more importantly on IPv6 implementation in Azure. Anything to watch out for with IP addressing, in particular IPv6.

Your help is appreciated.

Hi onlinerack,

When creating a public IP address you can select IPv4 or IPv6. While public IPv4 addresses can be assigned to several Azure resources, an IPv6 public IP address can only be assigned to an Internet-facing load balancer. The load balancer can load balance IPv6 traffic to Azure virtual machines. If you selected the Standard SKU, you do not have the option to select IPv6. You can only create an IPv4 address when using the Standard SKU.

For the IP Assignment, if you select IPv6 for the IP version, the assignment method is Dynamic. If you select Standard for SKU, the assignment method is Static.

Azure's default DNS contains both IPv4 A and IPv6 AAAA name records and responds with both records when the DNS name is looked up. The client has the choice of which address (IPv4 or IPv6) to communicate with.

Here are their Best Practices:

Thank you Blue Street Tech for the detailed answer. The only related question is what IP strategy would you advise for organisation about to build a hybrid cloud platform (VMware on prem and extending into Azure)

Sorry, I somehow missed your reply.

For your IP address strategy you may consider leaving IPv4 for the time being until MSFT can support that through the entire stack and support static IPs.

Also, consider how you are connecting to Azure:
