It's definitely "best practice" to turn off features you don't need. Who knows, maybe in five years someone will find a bad bug in the implementation of the IPv6 stack, then you'll be glad you decreased your attack surface.

Not saying this is what you should do, just a common rationalization.

It's also "best practice" to learn a new, foundational technology (like IPv6) sooner than later, perhaps less than 20 years after it was first available.

I know IPv6, just don't feel the need to use it. I prefer to have one firewall and public network interface to worry about. I can't disable IPv4 yet, so the logical solution is to disable IPv6.

Right and what is better way to learn than deploying random features to prod!

[icedchai]

Did I say they had to deploy it to production? If they deployed it in dev and test environments even a few years ago, they might have some experience deploying it in prod today.

It's only been ratified since 1998 and available as far back as Windows NT4

Pretty sure that's enough time to test it in development...
