Tips on deploying IPv6 at scale?

Hello /r/networking,

I'm really curious to see how everyone else is doing IPv6 deployments at an enterprise scale (if at all).

​

My questions are:

1. How are you assigning/tracking addresses throughout your environment?
2. How are you handling security without NAT? What kind of ACLs are you applying at the edge?
3. Any other gotchas doing this at scale?
