VM IPv6 Public Association

Prenote: I am new to Azure and networking in general. However, I have extensively read https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-network-interface-addresses and other docs regarding ip configurations and virtual network interfaces. It was recommended to me by support to make this forum.

EDIT: My goal is to use my Windows VM as a game server to host an IPv6 connection for iOS devices to connect too.

My goal is to connect to my Windows 2012 Server VM via its IPv6 address. I don't want a load balancer setup, just a VM with both IPv4 and IPv6 public addresses. I have a single network interface with two ipconfigs. The primary ipconfig has both a private and public IPv4 address, while the second ipconfig has a private IPv4 address. I am unable to edit my second configuration to include association for its public IP, it errors out by saying there are no "associable IPS". I have added an IPv6 address space in the vnet.

There are visible private IPv6 addresses and public/private IPv4 addresses, but, I am unable to associate the public IPv4 and continue. I have attached relevant screenshots.

    Greetings,

    You can assign zero or one private IPv6 address to one secondary IP configuration of a network interface. The network interface cannot have any existing secondary IP configurations. Each network interface may have at most one IPv6 private address. You can optionally add a public IPv6 address to an IPv6 network interface configuration.

    Note: You can't assign a public IPv6 address to a primary or secondary IP configuration.

    Here Is the doc on IPv6 limitations for better understanding.
