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 ...

The worst part is that most of these sites probably do have ipv6 addresses, they just didn't set up the DNS for it.

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.

What about 1 per car?

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")

And XP is already out of support and Server 2003 will next year. When will Amazon AWS end support?

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solve, so many entire /8 blocks are owned by single corporations, which should either be forced to sell or give up this outdated privilege.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...

Between 2008 and 2010, IANA was allocating 10 /8s per year. In 2010, they allocated 20 /8s. There are only 256 total in the system, and not all of those are even usable.

Rapidly-developing Asia already has about as many people as there are IP addresses by itself.

Where are you going to find enough /8s, how are you going to recover them fast enough to do any good, and who's going to pay the massive legal bills from the ensuing litigation?

Isn't IPv4 good for privacy? My IP address doesn't uniquely identify me unless you get records from my ISP. But wouldn't I be more likely to keep the same IPv6 address consistently?

It also makes it hard for websites to block users based on IP without also blocking lots of legitimate users sharing that IP. I think this is a good thing to keep the internet more equal and anonymous.

My provider (Suddenlink) support rep responded to my question about IPv6 support with "No, we do not support it since almost no one uses it currently." S

Perhaps you can point them to sites like http://www.worldipv6launch.org/measurements/ and show them some of the stats on networks that are using it. You can also point them to the fact that Facebook, Netflix, Wikipedia and all of Google's sites are available over IPv6. So the "almost no one uses it" doesn't quite fly.

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.

I would agree, and say that universities with an entire /8 probably shouldn't have them anymore either. That's a case where it definitely made sense early on, but stopped making sense quite a while ago.

IPv6 provides temporary addresses and privacy extensions - check your operating system for support.

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…

The nerdy t-shirt industry experiences a boost in margins, as they can now save ink by printing the much shorter "::1".
