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

It's a variety of space-filling curve.

That's enough to find out that this particular one is called a Hilbert curve.

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?

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.

I set up a dedicated server a few months ago. I was given, without even asking for it, a /29 (sort of 8 IPs), and could pay more for additional ones with justification like wanting one per virtualhost, etc.

This was not at a particularly expensive provider.

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.

A note on Rackspace: we see about 2–3% of the VMs we allocate come with only an IPv4 address. We have no idea why — we suspect it's a bug on Rackspace's side (we allocate everything automatically, through the same code path, so it isn't us!).

We currently only use the IPv4 address (I know, I know!), but it does present a bit of a problem when/if we decide to move.

> …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…

Yeah, Ford definitely does not need its own block

Who doesn't? I have my own /24 - registered back in the early 90's.

IPv6 is native and default at Linode.

But for some reason they don't set the AAA record for the default subdomain they give each instance, or they didn't last time I tried.

Ford has as much reason as anyone else to need a block. Consider subcontractors needing to connect to servers in a particular department.

Ford has an entire /8, a significant chunk of the entire address space. Ford does not have as much reason to need that much address space compared to, say, major ISPs.

Hasn't that been the case for a long time? I'm pretty sure I remember seeing stuff along the lines of, "If you'd like an additional IP address for your server, contact us and tell us why you need it" a decade or more ago.

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

The announcement in Feb 2011 was that IANA had allocated the last IPv4 address blocks from the planned allocations. IANA (ICANN) and the RIRs then worked to recover some blocks of unused IPv4 addresses. These became the "recovered IPv4 pool" and the agreement was that allocations from this pool would begin once one of the RIRs reached the last /9 of their available IPv4 address space.

LACNIC hit that mark and triggered ICANN's policy to start allocating out of this recovered address space pool. The NRO has an announcement up about this, too:

http://www.nro.net/news/iana-allocates-recovered-ipv4-addres...

Basically, after this recovered pool of IPv4 addresses is allocated by IANA, there aren't any more IPv4 addresses to give out.

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.

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.

Isn't it standard for 4G to give out IPv6? If everyone switched, we'd all have IPv6.
