This week APNIC delegated their last IPv4 address the conventional way. The remaining pool of IPv4 addresses in the APNIC region will be delegated in small chunks of 1024 addresses. There is in other words nothing left other than breadcrumbs in this region.

In contradiction to my very exact estimate of the IANA depletion date, my tool and the mathematics I have been using failed to predict the APNIC depletion date with good accuracy. The algorithms that I have been using were not very good at predicting how an over 300% increase in demand over the last 2 months affected the depletion date. I would have been better off just using a linear algorithm with the last 2 months of demand as my input.

I must say that I was very surprised how quickly the APNIC pool got depleted. It appears that a “rush to the bank” happened once the members in the region realized that they might not get any additional IPv4 addresses. As the graph below indicates, the APNIC average burn rate went from slightly below 400,000 IPv4 addresses per day prior to the IANA exhaustion to almost 1.2 million IPv4 addresses per day after the IANA pool was depleted…
