OS Win 2012 / SQL 2012
I'm trying to determine if IPv6 is needed, and within what capacity (traffic-wise, OS enabled-wise, etc.) to support Windows Failover Clustering for SQL AlwaysOn Availability Groups.
A proposal from a colleague is that it is, and they are referencing this article.
I do not gather from this article that IPv6 is needed, whether in the OS level or on the Core/Router traffic, for it to work.
But I did want to check in case I misunderstand what is needed, or how best to approach.
I don't want to open up IPv6 on all servers, or have networking have to open up IPv6 on the firewalls, if it's unnecessary.
Any advice/experience/input here appreciated.
