Description

I created VM using this template on 2 locations - southafricanorth and centralus. According to https://azure.microsoft.com/en-us/updates/ipv6-for-azure-vms/ , IPV6 is supported on Central US. IPV4 addresses were correctly assigned, but IPV6 not:
```
$ nslookup ipv4.southafricanorth.cloudapp.azure.com
Name: ipv4.southafricanorth.cloudapp.azure.com
Address: 40.127.3.15

$ nslookup ipv6.southafricanorth.cloudapp.azure.com
Name: ipv6.southafricanorth.cloudapp.azure.com
Address: ::

$ nslookup ipv4.centralus.cloudapp.azure.com
Name: ipv4.centralus.cloudapp.azure.com
Address: 52.176.100.161

$ nslookup ipv6.centralus.cloudapp.azure.com
Name: ipv6.centralus.cloudapp.azure.com
Address: ::
```
In azure dashboard ipv6 address was displayed as -.

Research direction

Start by opening the 201-load-balancer-ipv6-create template and compare its IPv4 and IPv6 configuration against Azure's IPv6-for-VM guidance. Reproduce the reported nslookup results in Central US; done means the template assigns an IPv6 address and the IPv6 hostname no longer resolves to ::.
