RE: [ipv6-wg] 2006 IPv4 Address Use Report
Hello all, I have been out of the IP field for a few years so forgive me if my question is about old news, but here it is: Is the decrease in the percentage of used IPv4 space in the United States of America due to other countries increasing their usage and/or the return of unused IPv4 space in the United States of America? Just looking at upcoming usage statistics globally. Thanks, Tanya Hinman, RN +1 919 272 1835

A year ago, the US held 1324.93 million addresses out of a total of 2238.04 million = 59.2% (apparently I rounded off incorrectly with my 60% figure). Yesterday's total is 2407.11 so for the US to maintain its 59.2% it would have to hold 1425 million addresses, which is an increase of exactly 100 million addresses. But the US didn't get 100 million addresses last year, but "only" 41.66 million for a total of 1366.53 (56.8%). So the US keeps growing, and still uses up a quarter of the new addresses given out in 2006, but the rest of the world grows faster so the US lead is diminishing.
I would think that an interesting statistic to look at would be the consumption rates by region and by the top 10 economy/country consumers in both IPv4 and IPv6. I would also look at the percentage of the allocated IPv6 resources by region and by the top 10 economy/country consumers. Ray

this makes sense to me. providers who received a /32 have plenty of space for some time (for most deployments). so they won't come back to registries. And the first movers did get their allocations in the first years. So this is a normal trend. Marc. ----- IPv6 book: Migrating to IPv6, Wiley, 2006, http://www.ipv6book.ca
