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

AFAIK some people gave space back to IANA and now even that is running out.

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…

The cloud provider problem is definitely real. I have an idea for a service that requires both IPv4 and IPv6, but Linode and Rackspace were the two I found that both support native IPv6. Otherwise, it's something involving a HE.net tunnel, which I'm not comfortable with for more than experimental use.

Here is the registry: http://www.iana.org/assignments/ipv4-recovered-address-space

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…

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.

Yup, IANA was allocating two /8's per month before they ran out. At best, you'd get a few months of extra time. http://www.iana.org/assignments/ipv4-address-space/ipv4-addr...

> It really, really pains me that so many cloud providers are taking so damn long to support IPv6. Does Amazon even support it yet?

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?

When I changed my home provider 6 months ago I didn't get a real static IP by default. I had to call them and explain why I would need one to get it. That may not sound like much but here in Bulgaria just a few years ago we used to get 2-5 IPs with faster home plans and 1 with even the cheapest. The pressure is slowly hitting the end users so it can't be that much longer until it becomes cheaper to switch.

Obligatory: http://xkcd.com/195/ Edit: I wish there was an updated version.

What is that way of ordering numbers called? If I knew the name I could google it but that's what I'm missing.

Yeah, Ford definitely does not need its own block

Ford has as much reason as anyone else to need a block.

Consider subcontractors needing to connect to servers in a particular department.
