IPv6 at AWS – Route53

Hooray! AWS users can now serve their DNS info over IPv6. You could serve AAAA records before, but only over IPv4.

This finally gives AWS customers a way to deal with IPv6-only customers (as are appearing in Asia), who might have otherwise had to depend on ISP proxies or CGN (Carrier Grade NAT), host their DNS elsewhere, or be unable to reach services hosted in AWS.

Register4Less now supports IPv6 DNS!

I got a great followup from my domain registrar Register4less today. A few weeks ago, I had asked about when their DNS would fully support IPv6.

They’ve allowed AAAA records in their hosted DNS for years, but they only accepted queries over IPv4 until this week.

This is just another reason that I love R4l’s support. When I had asked them about IPv6 DNS before, they said it was coming “soon”, but couldn’t give a for-sure date, but would let me know.

When they turned up IPV6 DNS this week, they proactively sent me an email letting me know that the service was available, answered a few questions (within literally 5 minutes!). is the official DNS provider of If you work IT, you should know this long-running webcomic.


Leave a comment – still no IPv6

Three years ago I wondered when would begin to support IPv6. The irony of hosting a blog that talks a lot about IPv6 on an IPv4-only platform is not lost on me 😦

Here we are in 2016 with Google, Akamai and pretty much all content providers are reporting more IPv6 traffic, and is still stuck in 1983.

This is not an OS issue, a load balancer issue, a PHP language issue, or even a WordPress software issue. I’ve seen WP software running full dual-stack, no problems. Five years ago. I’ve done it myself, I just don’t want to run WP myself anymore.

For whatever reason, has not decided to commit to the future. yet.


USA! USA! (unless you want affordable high-speed Internet service)

“In comparison with the rest of the developed world, the US has slower broadband speeds and higher broadband prices than just about anybody.”

No surprises here.  US ISPs and cable companies (among many other industries) continue to rock record profits, and instead of investing, just buy back their stock, or sit on the cash.

On the technology front, this means that instead of upgrading backbones, or delivering native IPv6, or a higher quality of service, they are deploying stopgap measures. Some examples of this are Carrier Grade NAT (CGN) instead of native IPv6. “Dumb” DVRs that are less programmable, and less usable than some home grown solutions. No investment in technical support.  Man-in-the-middle ad networks, DNS hijacking, abusive legislation, and other interference with their customers’ data.

As long as the last mile is a de-facto monopoly, that’s just what we’re stuck with.

Total Cost of Ownership of dual-stack IPv4/IPv6 and Carrier Grade NAT (CGN)

INET Denver was held last month at the same time and location as the North American IPv6 Summit.  The theme was “IPv4 Exhaustion and the Path to IPv6″.

I missed the morning talks as they conflicted with my advanced IPv6 class, but I did catch the afternoon sessions.

It seemed like there were three camps at INET Denver: people already embracing the future by deploying IPv6, people trying to avoid IPv6 as long as possible, and people who planned to make money from both of the other two camps.

Let’s talk about the “wait as long as possible” camp.

For almost two decades the argument from the “business side” of IT was there was “no compelling business reason to move to IPv6“. (That article is is from 2009 by the way, but I haven’t seen a new argument since then.) It’s true, there’s been no “killer app” that everyone demanded that was only available via IPv6. It’s also true that doing nothing was a legitimate strategy for quite a while. After all, what good is it to have a telephone (IPv6), if no one else has one? Until recently, moving to IPv6 truly didn’t have a compelling business argument. After all, doing nothing costs nothing.  Mostly.

The Internet has changed. And we’re (almost) out of IPv4 addresses, so you have to do something. Sadly, too many ISPs have tried to do what they think is the cheapest and most minimal amount of work they could get away with. That’s Carrier Grade NAT (CGN).

The economics have changed, too.  Lee Howard of Time Warner Cable had a very interesting talk where he deconstructed, and then destroyed the myth that CGN is cheaper to deploy than dual-stack.  Since he’s the Director of Network Technology for Time Warner Cable, I guess he knows more about the ISP business than most people.

Mr Howard’s talk shows that CGN will cost you in (unhappy) customers, support costs, and only delay the inevitable, when you’ll have to move to dual-stack anyway.  His talk effectively demonstrates that the infrastructure and operational costs of a CGN network are more expensive than dual-stack.

There’s your business case. Deploy IPv6 and save money. Done. Now get to work.

No knowledge of #IPv6 at DSL Extreme (@DSLX_Status)

I’m still on my quest for native IPv6 at home.  Today’s attempt: DSL Extreme. Result: FAIL

The pricing from DSL Extreme looks very attractive, less than half that what I’m currently paying Megapath. However, based on my call to DSL Extreme support, you get what you pay for. While Megapath doesn’t have any announced plans for IPv6, their sales people knew exactly what it is, and my SpeakEasy/Covad/Megapath DSL has had 2 outages (of less than an hour each) in 10 years.

Let’s start with the extent of the IPv6 info on the DSL Extreme web site. Searching for IPv6 leads you to a knowledgebase article on reverse DNS. First off, this page is a complete lift from another web site,, except DSL Extreme took out the formatting that makes the page readable. Second, there’s pretty much no IPv6 info on this page.

So, I decided to try their sales/support department. That phone call didn’t go well, either.

Tech support had never heard of IPv6. Period. Full stop.  Sort of.  At first they tried to tell me that their “dynamic addresses are v6 and static are the old ones.” Then I spent almost 5 minutes trying to get across the idea that there actually was this “new thing called IPv6” and that I wanted to sign up for their service if they supported it. The best I could get from them was, and I quote, “The only addresses we have are dynamic and static”. I guess they have both kinds of music too (country AND western).

I’m so very glad that my IPv6 tunnel to has been 100% rock solid. If it wasn’t for Hurricane Electric, it might be another year or more until I could start learning and use IPv6 at home. Thanks to them, I’ve already been running IPv6 at home for 13 months!

UPDATE:  The above was written Dec 28 2012.  Today (8 Jan 2013) I got a response to my query into sales, from about 10 days ago:

Thank you for your email. Unfortunately we do not provide IPv6 and as of right now we have no intentions of providing it.

No #IPv6 from Cox Communications (@CoxComm)

I spent entirely too much time the other day, trying to get IPv6 information from Cox Communications. It was not a good experience.

I spent about 10 minutes trying to find anything useful about IPv6 on their web sites.  I found a FAQ, which has some IPv6 technical information, but nothing about roll outs, trials, schedules or plans, other than “residential trials in 2013”.  At least that’s more than some other ISPs have been able to tell me.

So I decided to try Cox online chat “support”. This was so full of fail that I was compelled to share the experience. It looks like they’ve outsourced support to something called “”. While this conversation looks short, it actually took more than 8 minutes, and it looks like their support doesn’t speak English very well. I could overlook that, if they could answer my question.

Megapath – no #IPv6 plans?

I just got off the phone with Megapath sales, they have “no plans for IPv6“. That seems….. short sighted.

That was a very short phone call, 45 seconds. Their sales people know what it is, at least, and they know they don’t (and won’t) have it any time soon.

Our home network started ‘way back in the 90s with the first ISDN connection in our central office, dialing into SDSC‘s POP. A few years later it was upgraded to ADSL (the first in our CO, again), with SpeakEasy. SpeakEasy, Covad, and Megapath did a three way merger in 2010.  The service has been rock solid for almost 10 years, but it doesn’t look like the new entity will be moving forward.

The (residential) broadband options in our suburb are very limited: cable modem from Cox, or ADSL.  I’m close enough the central office that I could see it, if not for the trees, so DSL has been a good choice. I could get the theoretical max speed, if I wanted to pay for it. Since Megapath won’t be doing IPv6, I’ll have to shop around to see if I have any options for native IPv6.
