I am trying to find an IPv6 subnet calculator or even a "cheat sheet" that will help show how a /32 allocation is broken down into /40, /48 and /64 subnets. Has anyone found such a tool? I have been using the NorthStar web based database tool for dealing with my IPv4 allocations. While the author has mentioned support for IPv6 in the future, I am trying to get things rolling now. Any information is greatly appreciated.

Best regards, Jeff
