Goodbye IPv4

Tue Feb 01, 2011 8:43 am

IANA just allocated the last 2 free /8s to APNIC, triggering the remaining 5 /8s going to each of the RIRs as previously agreed.

So it's time to upgrade to IPv6 otherwise it will be The Day the Routers Died

Great video notfred. Put a smile on my face this snowy morning.

On another thought though, countries (and organizations) throughout the world need to stop waiting for the last minute to do things that are inevitable. We knew in the 90's the explosive force of the internet, and that IP addresses would be used up in 15-20 years. What would have been a much easier change back then is now going to be a much harder, costlier and longer process than it needed to be.

I know now I am just ranting but the same thing is going to happen with oil whenever that runs out. I understand that markets drive the cost and development but at the same time I think people need to step back and look at the bigger picture once and a while, and not wait till it's to late and then half ass a solution.

Sorry for my morning rant.

Well, any solution to this would border on (or outright be) religious, and therefore belong in a different forum :).

I believe that you've described how the majority of businesses and organizations are run. The people in charge are in it for short term gain. They'll let someone else worry about the long-term mess that they leave behind.

A lot (maybe most?) of ISPs' infrastructure isn't even IPv6 ready. There's a serious chicken-and-egg issue here, where nobody is feeling pressured to upgrade their equipment because everything else is still IPv4.

Combine that with a down economy (where nobody is willing to invest in new infrastructure) and you end up where we are today.

Of the big ISPs in North America, I'm only aware of Comcast rolling out IPv6 http://www.comcast6.net/ The story is different elsewhere in the world, I suspect APNIC has more usage than elsewhere.

Is there any real remaining reason why the Multicast blocks (224/8 - 239/8) and Future Use blocks (240/8 - 255/8) can't be put back into the pool?
What we have today is way too much pluribus and not enough unum.

I believe it was Ars that had a good write up on why, but what it basically came down to was the fact that all software expects those blocks to be unused, and throws exceptions if they are. If you're going to spend the time developing code that correctly accepts the blocks, why not just fix up the code to use IPv6 instead.

Multicast is actually used in most of the IPTV stuff. And as emorgoch says, if you are going to change the code why not change it to IPv6 anyway? The Future use block is only 15 /8s anyway and IANA was allocating a /8 every 4-6 weeks so that wouldn't give you much room anyway.

What will it take?

Tue Feb 01, 2011 10:16 am

What will it take to transistion to IPv6?

As a serviceman working in communications, I know that literally every peice of equipment we employ (emphasis on we, my unit) is IPv6 capable. So, as a novice to real internet infrastructure, can anyone share a quick explanation as to what it will take to flip the switch?

Re: Goodbye IPv4

First of all the ISP needs to get IPv6 space allocated just like it has IPv4 space allocated. Then the ISP needs to sort out IPv6 peering (are all of its peers IPv6 capable, does it need to negotiate new agreements to allow for IPv6 etc). Then there is nothing technically to stop it running clients on dual-stack IPv6/IPv4 although they probably want to get their address assignment and billing sorted out to deal with IPv6 (to stop people doing tons of data over v6 and not getting billed for it).

After that they can begin the slow process of migrating their systems (mail, web etc) over to be dual-stack and hence accessible from IPv6 only hosts. Probably the biggest amount of work is making sure that all the backend management, logging etc systems can cope with IPv6 addresses.

The summary at Ars from last year is probably the best "quick" explanation. They have some older articles that offer more background if you search.

I don't see the reason why the networking crowd should be panicking. The major backbones and hubs of the internet will be upgraded long before there will be "actual" problems.

But until the client systems (i.e. the broadband routers in people's homes) are upgraded as well you can't utilize the additional IPv6 address space effectively, because any IPv6-only sites will be inaccessible to a large percentage of Internet users.

Well that's been the attitude for the past 15 years. We've just reached a major milestone along that path and as I pointed out earlier I'm only aware of one major ISP in North America that supports IPv6. Roll out of IPv6 takes time, how long do we have to wait before we start seeing those upgrades?

When there is enough demand for it to justify the infrastructure costs. Read: it doesn't exist yet. Cisco and other networking equipment companies are foaming their mouths with the opportunity that comes with the big upgrade. ;)

The problem is mostly software for client systems. A simple firmware update on most customer-grade routers will do the trick. The real problem is getting average joe to upgrade. ISP will have to launch some of upgrade campaign akin to digital TV movement. It helps that the majority of current OS and NICs have IPv6 support.

You really think that Linksys/Netgear/etc. are going to issue firmware updates for all of their old routers? Netgear hasn't touched the horribly buggy firmware in my router since 2005. If they're not even going to fix blatant bugs, I'd say the odds of an IPv6 firmware upgrade are within epsilon of zero, for any router that isn't in current (or at least recent) production.

Honestly, there's no real reason to get new hardware when the old stuff is perfectly capable of it.

In fact, they have a huge economic incentive not to do this. When consumers (eventually) start discovering that there's "more internet" out there that's inaccessible to them except via IPv6, their router mfr has every reason to say "Yes indeed, and we'll be happy to sell you a new router that lets you get there!" After all, you don't get a free upgrade to your CPU when new ones appear, and 802.11b/g users didn't get a free update to n, etc. It doesn't matter that a firmware upgrade is all that's required; they have no obligation to provide one. And short of such an obligation being created (ie, government regulation and mandates, à la digital TV) they won't. cha-ching

But it's going to be a long time before that "more" IPv6-only internet exists, because who wants to have a site or service there, where it's currently unreachable by the vast majority of potential eyeballs or customers? Sure, you might want an IPv6 address for the future, but you want an IPv4 address for the present... and that present never ends. Meanwhile, the folks who hand out the IPv4 addresses have to figure out how to ration their finite (and in some cases exhausted) supply. I suspect we'll see all sorts of NAT-ish things going on where the Telcos/Cablecos end up giving their customers "fake" IPv4 addresses so that they can provide actual IPv4 IPs to their business customers (most already charge extra for a static IP; charging extra for even a dynamic but real IPv4 IP is the next step). Of course, that NAT stuff will generally break all sorts of things from games to torrents -- but hey, you want that to work? Well, then pay extra. You can still surf the web, after all. You want to any of that fancy-schmancy "advanced" stuff? cha-ching (And in fact, since many of the big ISPs like Comcast are also in the content-distribution business, they may not even offer that at any price. Sorry your torrents don't work, but we'll happily sell you video-on-demand)

In fact that might be the only thing that will push end users into IPv6, if it allowed them to go around some of that pain. It would be nice if the ISPs incentivized that transition by not also charging extra to do any of that via IPv6, but I seriously doubt they'll be able to resist.

The ISPs get those complaints, not the router mfrs (after all, in this case the internet isn't broken, just incomplete). And the easiest answer the ISPs can give is "your router is out of date, get a new one." They might suggest a firmware upgrade, but again, there's no reason for Cisco to develop a firmware upgrade for a 10-year-old LinkSys router when they can just tell you "Sorry, but did you know for very little money you can get a new router that's even better?"
Honestly, there's no real reason to get new hardware when the old stuff is perfectly capable of it.
No, but unless you have a router with 3rd party firmware, there's no guarantee you'll be able to make your old hardware do it, regardless of what it might be capable of.

How much you wanna bet they just tell their customers to buy a new router? Win-win for them -- they don't need to develop the firmware update, and they get to sell more hardware!

Honestly, there's no real reason to get new hardware when the old stuff is perfectly capable of it.

It isn't "capable of it" (in any practical sense) if the firmware doesn't exist. Even if there's 3rd party firmware available, the average end user isn't going to know how to find or install it.

Seriously! This is a ready-made marketing campaign, I can already envision what the "Supports IPv6!" sticker graphic will look like...

The notion that they're going to upgrade all the out gateways out there is nothing short of delusional. That's throwing money away.

/notapersonalattack

Glorious, it's posts like these that make me think you actually are a raving lunatic. Of course, then I perform a self-analheadectomy and realize that you're right, and that the easy/right/good answer is not the logical one, and I am made sad.

I can't imagine a peice of consumer networking equipment manufactured in the last two or three years that doesn't already support IPv6; it's hard to imagine other companies, such as ISPs, providing incapable or unupgradable equipment to their herds, at least in the case of people who rent their equipment. Backbone equipment, on the other hand, I have no concept of :).

Just because you can't imagine it....

From what I can tell, there's a lot of consumer DSL equipment still going out the door today without IPv6 support. The popular Netgear DG834 series still doesn't support it, despite being on its 4th revision. And I think that's the situation with consumer modems from most DSL providers. Just looking at QWest (my local telco) for example, I don't think any of the DSL modems they currently offer support IPv6. In fact, you'd be hard-pressed to find any mention of IPv6 anywhere on the consumer side of Qwest; they have this press release
QWest wrote:
To stay ahead of the Internet’s explosive growth, Qwest Communications (NYSE: Q) today announced it is offering public and private Internet Protocol Version 6 (IPv6) addresses to its government and business customers.
That's from July 2010, seven months ago -- yes, you're certainly staying ahead of the internet, QWest! That press release also goes on to mention the government Networx program, which makes me suspect there was actually a requirement to support IPv6 in the later stages of those contracts (the largest civilian government telecoms contracts in the US, which QWest got a piece of) and that was the only reason QWest got even that much on the ball.

I know less about the cable side of things, though it seems to be in somewhat better shape; certainly, the DOCSIS 3.0 devices I've looked at seem to have IPv6 support. But they are by no means the only devices out there, and I suspect at least some of the cable operators were still offering boxes without IPv6 support until fairly recently (and in some cases maybe still are).
