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
Goodbye, IPv4 IANA Starts Allocating Final Address Blocks

Re: Goodbye, IPv4 IANA Starts Allocating Final Address Blocks
#12This 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...

Edit: I wish there was an updated version.

Great strides could be made if Google, Wikipedia, and other major destinations had a day where they displayed a box to non-IPv6-enabled visitors telling them to contact their ISPs and ask for IPv6 and explaining why.
Great strides will be made when the cost of each IPv4 address rises significantly. That's when you'll see real progress, though not necessarily in the right direction.

#14I'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?
It becomes more and more impossible every day. Last time I tried to acquire a new IPv4, the distributor (my VPS host) required a technical reason for the request. If the request wasn't up to par, you would be denied an IPv4 + given an IPv6.
Have you ever been denied? My understanding is that hosts are required to justify usage, but that they aren't exactly scrutinizing that document.

Even if a block is not publicly advertised, it is still entirely possible that it is used internally. Using the 10/8 range was not common place, and certain organisations have IP's that are technically publicly routable in their internal infrastructure.
As for 44/8, there are still those that use it, taking it away would mean having to renumber all of the equipment on that network...
No, trying to reclaim IPv4 addresses by making people go through herculean efforts to renumber their networks is not the way forward and simply delays the inevitable. IPv6 is the way forward, start pushing that, and get more people using it.

It's trivial to get new IP4 addresses on AWS and Rackspace. I guess it depends on the company. Microsoft's Azure does a weird thing where instances all share the same IP but are accessible via different ports when in a group.

Yeah, Ford definitely does not need its own block

Probably the same day that the Voyager spacecraft finally leaves the Solar system. What I mean by this, is that the line is really fuzzy -- you can always buy a block of IPv4 addresses, if you pay enough.

If only there were sites / protocols that everyone wanted, which could only be reachable by IPv6. Maybe a new file sharing protocol, which uses the vast IPv6 address space to hide better, or something like that.

Depends on the RIR that assigned your block. RIPE For example requires you provide a technical reason, AWS gets around this by saying that technically every instance could have an SSL certificate and thus should have it own IP for compatibility reasons. RIPE will and has reclaimed /24's and /16's from LIRs who didn't follow their guidelines (tl;dr of which is "must be a technical limitation of IP sharing")
