There are several scenarios with Exchange 2010 that require IPv6 to be enabled.
Microsoft has made it clear that, with the recent operating system versions (2008 and 2008 r2), they are doing testing with IPv6 turned on and you MAY have anomalous results if it is turned off.

In fact, you will find more data out there suggesting it is disabled if not in use because it causes odd things to happen...

I haven't paid particularly close attention, and forgive me for posting without having all my ducks lined up, but aren't there some things that break by disabling IPv6?

My ISP isn't supporting it yet, I'm not using it internally yet. Am I better off removing IPv6 from the interface(s) or doing a ULA (even though I don't know what I'm doing or what I'll eventually want to be doing).
