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.

Try the Net::IP perl module on CPAN. It comes with a nifty little script
that lets you cut the original prefix into a set of smaller prefixes.
