So what exactly is the "IANA IPv4 Recovered Address Space"? Today's news sounds almost exactly like February 2011 when the IANA announced that it finally allocated the last remaining blocks: http://www.nro.net/news/ipv4-free-pool-depleted
There are unallocated /8's that are privately routed. A lot are controlled by the U.S. DoD. But every time they come up, the response is always "so what? use IPv6!" I generally agree. Putting those in circulation would actually be a bad thing. It would allow IPv4 to continue to zombie-walk for another couple years, maybe another decade, and in so doing to become more deeply entrenched, harming us in the long-run. IPv…

So what exactly is the "IANA IPv4 Recovered Address Space"? Today's news sounds almost exactly like February 2011 when the IANA announced that it finally allocated the last remaining blocks: http://www.nro.net/news/ipv4-free-pool-depleted
It is space that has been surrendered to IANA for re-allocation.
This is the recovered pool that's finally running out, so short of reclaiming something drastic like the class A block 10 (you know, a really really bad idea), dang. Anyone know what IPv6 adoption is looking like these days? Google is showing like 3% of their connections are native to it [1], which does not look promising. 1: https://www.google.com/intl/en/ipv6/statistics.html#tab=ipv6...
> …short of reclaiming something drastic like the class A block 10 (you know, a really really bad idea), dang. 10/8 is off limits, but there are a bunch of /8 blocks which could likely be reclaimed if we really needed to, including: - About half a dozen which were allocated to the US military in the early 1990s, most of which aren't even publicly advertised at all - 44/8, reserved for amateur radio - A number of othe…
It would take years to arrange the return of 100 million addresses compared to the demand for a few billion addresses with even conservative growth.

Claiming back /8s from companies won't work. 16 million addresses is just a drop in the bucket compared to growth in China, India and other countries. It would take years to arrange the return of 100 million addresses compared to the demand for a few billion addresses with even conservative growth.

I don't work at Amazon, but I spoke with someone about this recently, and I believe the issue is that Amazon provides virtual hardware and a virtual networking stack, and the tooling required to virtualize the networking stack in IPv6 isn't mature enough yet.
For providers that offer dedicated hardware, this isn't an issue, but Amazon's services abstract over a very complicated and intertwined stack, so I can understand why it would take them longer.
I've seen headlines like this for literally 5 years at least. "IANA finally out of IPv4 addresses", "IANA allocates last X block", etc. When will it finally be impossible to buy an IPv4 address?

Yeah, Ford definitely does not need its own block
Consider subcontractors needing to connect to servers in a particular department.
