I know that this isn't a Cisco specific question, but I'm curious as to how I would go about reserving a block of IPv6 addresses for my company. I have seen some people suggest on other forums that we're supposed to use the ISP supplied addresses. However since NAT isn't a part of IPv6 then we would be at the mercy of our ISP and could never change ISP's without a painful IP address change internally.
Thanks in advance.

Take a look at http://blog.ioshints.info/2011/02/ipv6-provider-independent-addresses.html
You have a few options.
- Get Provider Independent address space (you need to be multi-homed, plus a few other requirements)
- Trust that renumbering is easier in an IPv6 network
- Look at solutions like LISP
- use NPT66 (1:1 IPv6 NAT)

To reserve an IPv6 address block, contact your local regional registry.
For the United States, for example, see https://www.arin.net/fees/fee_schedule.html
