This is a red herring. As the IANA free pool neared its end, APNIC alone was going through approximately 1.5 /8s per month, in addition to the approximately 0.75 /8s per month in the RIPE region and 0.5 /8s per month being consumed in the ARIN region at the time plus miscellaneous consumption in the LACNIC and AfriNIC regions. The most optimistic estimate I’ve ever heard for reclaimable (unused/fallow) IPv4 addresses was 24 /8s worth. Let’s round that up to 32 /8s to make the math easy and make sure we are overly conservative. Now, let’s compare the amount of usable lifetime IPv4 gets from reclaiming all those addresses to the time and manpower it would take to do so… First, the most optimistic estimate for reclamation I ever saw was ~80% over the course of about 5 years, assuming complete cooperation, no litigation, and rapid, painless, unambiguous identification (each and every one of which is utterly impossible in the real world). 25.6 /8s. With a burn rate north of 2.75 /8s per month, that’s a life extension of approximately 9 months. Under the above overly optimistic assumptions, the minimum (again most optimistic) estimate was that each RIR would need a minimum of 10 FTE working the process to achieve those numbers (as if they were even possible). Let’s assume we only really need these efforts in the larger 3 RIRs and leave LACNIC and AfriNIC alone for the moment. That’s 30FTE * 5 years = 150 FTE Years at 2000 hours per year = 300,000 Man Hours. Each and every person who has looked at this in any depth has come to the conclusion that there’s a lot more to be gained from those 300,000 man hours going into deploying IPv6 than could possibly be achieved by sinking them into reclamation efforts.
