I've often read in Azure documentation that it is not recommended to make any changes to the VM network from within the guest OS NIC settings. Cool. But then I come across this doc I see the note as "For best performance, when you are using Azure VMs as DNS servers, IPv6 should be disabled."
1. What is the technical justification for this statement?
2. How do I disable IPV6 on a VM without touching the guest OS NIC settings which you guys tell me not to touch. Am I missing something?
