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.

SoftLayer has supported IPv6 for years. All their servers have IPv6 enabled.

It would be nice if certain websites we all use every day supported v6 better... firstmillion:~▻ host -t AAAA news.ycombinator.com news.ycombinator.com has no AAAA record firstmillion:~▻ host -t AAAA twitter.com twitter.com has no AAAA record firstmillion:~▻ host -t AAAA cloud-images.ubuntu.com cloud-images.ubuntu.com has no AAAA record firstmillion:~▻ host -t AAAA ubuntu.com ubuntu.com has no AAAA record ...

It sure would be. Here's a list that does: http://www.worldipv6launch.org/participants/?q=1

BTW, there is a nifty Chrome extension that tells you whether the site is doing IPv4 or IPv6. Always nice to see a green 6 in the address bar.

Easy problem to solve, so many entire /8 blocks are owned by single corporations, which should either be forced to sell or give up this outdated privilege. Does Xerox really need all of 13.x.x.x? Or Ford Motor Company all of 19.x.x.x? http://en.wikipedia.org/wiki/List_of_assigned_/8_IPv4_addres...

And how long will that last? And there's a presumption here that businesses with lots of IPs that got in early aren't already selling them for fun and profit. They, such as Nortel, already are.

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.

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")

So they could recall most of Amazon's IPs due to lack of SSL? Fun to watch!

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.

LTE is in large part about IPv6 (with the aim of using the PS IPv6 net to move all audio/video longer-term), often with carrier-level NAT for IPv4, simply because unlike the incumbent telecos, many mobile operators simply don't have many IPv4 addresses and there isn't the pushback against carrier-level NAT on mobile.

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.

I would argue that Ford (and the other multinationals) have more need of an /8 than any university that is just in a single city.

A /8 is 16,777,216 addresses.

Ford has 181,000 employees as of 2013 (http://en.wikipedia.org/wiki/Ford_Motor_Company).

That's very roughly 92 publicly routable IP addresses per employee.

I highly doubt they need that many.

So there is a lot of sentiment that I've been hearing over time about when exactly will IPv6 become a thing. Here's how I see it: Step -1: We started running out of IPv4 addresses. The internet is IPv4-only for all practical purposes. Nobody is doing IPv6 because it's still experimental. Your weird neck-bearded friends are talking about it, that's about it. Step 0: Inception! IPv6 is now a standard and you can route…

Are we currently in step 3? How much does a /24 running for right now?
