In the following I'm assuming that you're familiar with the fact that staying on the 4-byte boundaries makes sense because it makes reverse DNS delegation easier. It also makes the math easier.
I assume you meant 4-bit. ;)
Grrr, I hate when I do that. I spent quite a bit of time on this post, and the one time I remembered that I needed to go back and double-check what I wrote there I wasn't at the keyboard. Thanks for keeping me honest.
There was one other thing you wrote that I wanted to clarify, you indicated that I was arguing for ISPs to only get one shot at an IPv6 allocation. Since my post was already really long I chose to leave out the bit about how (TMK, which could be outdated) the RIRs are reserving a bit or two for their allocations to ISPs so going back and expanding should be an easy thing to do. On a personal note, I hope that we DO need to expand IPv6 allocations to ISPs as this thing finally gets deployed.
My understanding is that the RIRs are doing sparse allocation, as opposed to reserving a few bits. I could be wrong. -- Nathan Ward
