> I have multiple static IPv4 addresses and they have suited me just fine for decades IPv6 is for the people (countries, continents) who did not get in early on the IPv4 address gold rush. Your take is basically "got mine, F you".

Or ... people can use the DoD/Mod and assorted other space to get their IPv4 allocations. There is a ton of unused space in IPv4. Reserved, allocated but entirely unused. Also take back some /8's from greedy companies that don't need all that space. stares at HP When I say take I mean take as in a forceful annex and a timeline.

Also take back some /8's from greedy companies that don't need all that space. In our exponentially growing world that wouldn't help. By the time we ran out of Class As we were allocating a new one every month. Reclaiming all the unused addresses would barely make a dent in demand.

  > There is a ton of unused space in IPv4. Err... you do realize that the number of humans currently living on planet earth is twice the number of IPv4 addresses... right? We can't all have an IPv4 address for each of our devices. We can't all even have one IPv4 address, period. But maybe they should just try not being poor, eh?

  You have to be really special if you think a 32-bit address space can cope with the ever expanding internet. We only managed to scrape by for now because ISPs keep on putting more and more people behind CGNAT. (My country's ISPs forced the migration to CGNAT because they literally couldn't get more IPv4 blocks without spending a hefty amount)

    You have to be really special I am very special, mama said so. I stand by what I said. Get countries to do what I said and DHCP will take care of the rest. CGNAT can be binned once people do what I said.

      DHCP? For country-level IP allocation? Yeah, your mama was not wrong - you indeed are a special one. Now, let's bring you to a nearby playground...

        DHCP? For country-level IP allocation? No, that would darn silly. For ISP allocation like all normal ISP's. Gosh golly friend.

Someone did the math on this: > Now, average daily assignment rates have been running at above 10 /8s per year, for 2010, and approached 15 /8s towards the end. This means any reclamation effort has to recover at least 15 /8s per year just to break even on 2010’s growth. That’s 5.9% of the total IPv4 address space, or 6.8% of the assignable address space. Is it feasible to be able to reclaim that much address space? Even if there were low-hanging fruit to cover the first year of new demand, what about there-after? Worse, demand for address space has been growing supra-linearly, particularly in Asia and Latin America.

Even if you (CG-)NAT an IPv4 address for some number of people, you still need to have IPv4 addresses for public services (web, mail, NTP, etc).

    There are 'only four billion IPv4 addresses, and there are eight billion people on the planet. There are just as many smartphones (I have two: personal and work) Unless all of these devices are running a dedicated full time server that must be reachable inbound by everyone this is not required. At any given time "all the people" are not online. That is why DHCP (per ISP) takes care of this. Maybe some day all the people may become terminally online but I would not count on it. Yeah some day IPv6 may be required. Maybe in 100 years or so. IPv4 has plenty of unused allocated addresses that can be ripped away from greedy people. There was a time when ARIN would check to see what was in use and would take back anything people were squatting on. I think the reclamation project works if we dont assume everything has to be reachable as a server. I should add that cell phones (where people are terminally online) were already IPv6 a long time ago for the most part so it's really a non issue. The only risk I see is if someone wanted to start a new massive dedicated server and VPS provider. Most of those are dual stack IPv4+IPv6 now and doing that means clawing some IPv4 space away from those I mentioned earlier.
