I haven't requested anything yet. That's why I came to you folks. To learn and then get busy on it. Thanks for your top-down and bottom-up idea. I will probably also intersperse /56s in between allocations as well; filling them in later if it ever gets to that.

If you know that you're going to need more than a /32, be sure to ask ARIN for more than the default. But these things are almost impossible to get right the first time, so don't sweat it if you have to come back for more later. There are more than 8 prefixes per AS for IPv4. One prefix per AS for IPv6 is a laudable goal, but it's not a huge deal if it's more like 2.
