June 6 Is World IPv6 Day 2012: This Time For Keeps 463
An anonymous reader writes "On 8 June 2011 many companies (big and small) enabled IPv6 to their main web sites by published AAAA records; 24 hours later, almost all of them disabled it after the test was done. This year, on June 6th, many of those same companies (Google, Bing, Facebook) will be enabling IPv6 again, but this time there won't be any going back. In addition to content providers, several ISPs are also participating: Comcast, AT&T, XS4ALL, KDDI, and others. CDNs Akamai and Limelight are on board, as well as network equipment manufacturers Cisco and D-Link. Is the chicken-and-egg problem of IPv6 finally, slowly coming to an end?"

This is incorrect. There are a number of IPv6-only services, especially in the asian markets, where IPv6 has been available to clients for a goodly number of years.
The alternative to IPv6 to work around the problem with NAT.
This isn't an alternative. NAT expands tha number of clients that can use the internet, but is largely useless on the server side. APNIC has run out of addresses, RIPE is going to run out this summer, at some point its going to become impossible for datacentres to get new IPv4 addresses, and at that point anyone runing servers is going to start having problems. They will start by shoving services behind proxy servers, etc. to reduce the number of IPv4 addresses that need to be exposed, but this only goes so far. Some services can't be placed behind proxies, running services on non-standard ports is almost as problematic as running them on IPv6 (a large proportion of customers are behind restrictive firewalls). At some point, IPv4-only clients are going to become second class citizens - they will be able to access the internet, but some services will be unavailable to them. Yes, it will take many years, but it will slowly happen.
Oh, and on a private network, which is behind a NAT anyway, there is even less reason for IPv6 - Yes, I do have enough 10.0.0.0 addresses for my home network.

Why? One of the really big benefits of IPv6 is the lack of address translation. This means stuff like peer to peer services (e.g. VoIP) can work without having to use unreliable nat traversal technologies such as STUN (peer to peer systems have to exchange addressing information. If there is no NAT then they just look at the local machine's address. If there is NAT then they have to use various techniques to probe the NAT and then make an educated guess as to what IP address and port their traffic will be translated to). If you try to perform some non-standard NAT at the border, you're going to reintroduce a lot of problems that IPv6 was built to avoid, and you also introduce an overhead of having to manage the NAT.
Eventually -- which probably means "the next version of Windows" given how IT seems to work these days -- IPV6 will be phased in even internally.
Why wait for the next version of Windows?

Allow me to point out a couple of IPv6's features for you:
- IPv6 is designed to be hierarchical, so knowing the location of a segment will be easier than IPv4. Each /64 is routed under a matching /48, which is under a /32, etc..
- All subnets should be /64's
- IPv6 does not use broadcast IPs. It has various multicast addresses with the prefix ff00:/8 to address the link-local domain (~=broadcast), site-local domain, etc.
- Don't think of "wastage". By design every subnet should be a /64. The host address is intended to be globally unique, so there are 2^63 available globally-unique host addresses that by design can move to another prefix and still be unique within that prefix. If you don't want to use a globally unique ID, there are also 2^63 non-globally-unique IDs, and for example prefix::1 is one of them. By your thinking the IPv6 waste is colossal, but it's not waste, it's a design feature which allows hierarchical routing and collision-free merging of subnets.
- Routers need not take up a public IPv6 address if you're that desperate for space (which you aren't, I promise). All IPv6 hosts have a link-local address (think 169.254.0.0/16, but always there), and the router can advertise a route on the link-local address

This is one of the core problems with IPv4 (which CIDR) skirted around.

Heck, Hurricane Electric assigned me a /64 IPv6 subnet (2^64 addresses available)

No, an IPv6-only device isn't going to be able to talk to an IPv4-only server (unless it uses a NAT64 gateway to do so). IPv4 is not going to suddenly disappear, dual-stacked clients are the norm, and as IPv4 addresses become harder to get hold of, ISPs will use carrier grade NAT to provision IPv4 to their clients. Talking to IPv4-only servers will still happen over IPv4.
Address exhaustion is largely a problem for servers, where NAT isn't really feasible. For many years to come, clients will have (NATted) IPv4 and (unNATted) IPv6 concurrently. Which is why it makes no sense when ISPs say "we don't need IPv6 because *we* have plenty of spare IPv4 addresses" - it doesn't matter if you have a big stack of spare IPv4 addresses if the people who operate the servers that your customers connect to don't.
What *should* have happened, is the telecoms regulators should have mandated that ISPs implement IPv6 support and sell IPv6 capable routers a good number of years ago since it was clear they were going to wait until crunch-time before bothering to do so without regulatory pressure.

As much as I hate to nit pick one specific company, but Amazon Web Services is used by a LOT of people and groups, are they going IPv6? I know their Elastic Load Balancer is, but what about everything else? Is Route 53 v6 glued? v6 accessible?
More importantly what about CloudFront? Try going v6 only now and you'll have a lot of "functional" websites which look like hell because they use Akamai or CloudFront which aren't v6 enabled (Though Akamai has commited)

How will the avalanche fall? (Score:5, Insightful)
I hope that some of the network/systems analysis companies out there are taking accurate notes about the state of what's accessible via IPv6 and IPv4. I think we'll see an interesting sort of "avalanche" graph when we reach the tipping point. Or not -- perhaps there will be enough dual-stack that we'll just have a slow deathmarch of sites available by IPv4, with a few less year after year?
But to step back and wax lyrical about the whole problem, the reason that IPv6 hasn't taken hold yet is because it just hasn't gotten enough of an IPv6-only install base clamouring for support on their popular websites.
Having major websites and hardware manufacturers on board is an important piece of the puzzle, but it's nothing compared to money. Get enough people inconvenienced that they will take their eyes and their money elsewere (directly, or through advertising revenue on sites, etc...), and every site that cares about their viewership will hop on the IPv6 train. Of course, this means that Bob's website that features his personal Banana Sticker Collection might not get IPv6 support until his ISP drags him to an IPv6 address, kicking and screaming all the way.
That whole idea a year or two ago about putting out a big zip file of porn, but only available on IPv6, was kind of a hoot. AFAIK it never came to fruition, but I liked the creative thinking there. Has anyone else had any crazy good (or just crazy) suggestions about how to spur IPv6 adoption?

For those that think NAT is some kind of security feature I suggest learning what it actually is instead of throwing three letters around as some sort of incantation. The features actually come from the firewall that just happens to be on the same physical device that gives you NAT and you still need something like that device anyway to get the net into the office with IPv6. The firewall isn't going to go away, just NAT (network address translation).

While it is true that NAT itself isn't a security feature, being limited to only a single IPv4 address and being forced to hide all devices behind a single IP address actually is. With a typical single-IPv4 address NAT network you simply can't expose all your devices to the Internet, it's impossible. It's secure by default and there is not even a way to missconfigure it. At worst you can expose a few selected services to the Internet or a single machine, but not much more.

Finally, an end to Google's daft IPv6 policy (Score:5, Interesting)
Did you know that for the past three year Google has actually published AAAA RRs for its online properties? However, the catch is that they won't serve you those as a response unless your /32 is on the list of vetted ISPs.
Even if you query one of their public IPv6 resolvers ( e.g. 2001:4860:4860::8888 ) you'll not see a AAAA for YouTube or Google+ unless you're on the list.
To pass the vetting an ISP has to demonstrate various technical aspects such as redundant, othogonally-routed global routes to Google's servers. For small ISPs such as mine, who have worked to implement native IPv6 connectivity, this is simply a step too far. So a proportion of the IPv6-connected world has to fall-back to v4 to talk to Google.

Well there are a lot of broken broadband setups too, with hideous line noise and lag, but I don't see Google withholding access from those people.
The point isn't to withhold access, it's to make sure that when people with broken IPv6 setups try to use Google services, those services actually work as well as everything else on the web.
All web browsers and most other Internet apps these days will try IPv6 first if DNS reports an AAAA name. If IPv6 doesn't actually work, though, you'll get nothing at all until the connection times out and the browser falls back to trying the IPv4 address.

The major operating systems support IPv6 Privacy Extensions. This means they generate and use multiple temporary IPv6 addresses, making them less identifiable than most IPv4 systems.
Also, there's no requirement for IPv6 addresses to be fixed. Just as some ISPs offer dynamic IPv4 addresses now, some ISPs will offer dynamic IPv6 blocks in the future.

Privacy isn't the responsibility of IP (Score:4, Insightful)
NAT provides only the illusion of privacy; the problem isn't the addressing, but rather the huge centralized systems that we have come to depend upon and which are controlled by only a handful of entities.
Meaningful privacy assurances require effort, and must be addressed at the application layer. This is best served by crypto and peer-to-peer communications, and keeping third parties out of the loop. IPv6 offers the possibility of restoring the most important and fundamental property of the Internet: the end-to-end principle. (If you haven't already, please read this [worldofends.com].) IPv6 provides the basic foundation for applications of the future, allowing one to build in as much security, privacy, and anonymity as they may want. To communicate freely and on your own terms.
The only lemmings I am worried about are the ones who needlessly cling to NAT, and would willingly cripple their own IPv6 networks with similar restrictions. The primary value of the Internet, is that it allows everyone connected to be an equal participant. Once you hoist a NAT (or overly zealous firewall) in front of your connection, you are turning yourself into a mere client, subject to the whims and abuses of some service provider.

First of, NAT provides no privacy, it's just a hack to allow you to use multiple devices behind a single IP, so while it might hide what device you are using, it doesn't hide the fact that you own that IP. What provides privacy on IPv4 are the dynamic IP addresses that you almost always get, as static IP addresses are an premium-only service. And those dynamic addresses don't just provide an illusion of privacy, they provide pretty real one, not unbreakable of course (cookies, Facebook-like buttons, browser

For starters it will allow you to host a bunch of services on different machines without having to put them all on weird ass ports because you only have a single ip. Peer to peer software will work as intended without nasty hacks to poke holes through the nat.
It essentially stops the internet from becoming broken into a one-way thing, which is one of the side effects of nat.
