But see, I'm a cable company, and I want a /48 per customer, and I have a couple of hundred thousand per pop, so I need a /30 per pop. Oh, and I have a few hundred pops, and I need to be able to aggreate regionally, so I need a /24. By my calculations I just used 16M /48's and I did it in about 60 seconds to write a paragraph. That's about 279,620 per second, so I'm well above your rate.Fine. You got ARIN or somebody to allocate your *first* /24 in under a minute. Now how long will it take you to actually *deploy* that many destinations? And where do you plan to get your customers for the next 4 or 5 /24's, and how long will *those* deploys take? Face it Leo, you can't *sustain* that growth rate.building in a lot of aggregation. Remember the very first IPv6 addressing proposals had a fully structured address space and only 4096 ISP's at the top of the chain!How many Tier-1's are there now, even if you include all the wannabes? And how long would it take at current growth rates of Tier-1 status to run out the *other* 4,087 entries?
RIRs allocate to lots of non-Tier-1 organizations, so, that count is pretty meaningless no matter what definition of "tier 1" you decide to use. I suspect that there are probably somewhere between 30,000 and 120,000 ISPs world wide that are likely to end up with a /32 or shorter prefix. Owen
