In recent months, there have been presentations at some of the big Internet gatherings by Time Warner Cable engineers about IPv6-only access networks. The first was by Wes George at IEPG/IETF in October 2013 (slides). The second was by Lee Howard at RIPE 67 (video, slides). Seeing these presentations reminded me of my own foray into this realm a couple years ago.

ARIN 32: A call to content providers

This week I remotely participated in ARIN 32. This was the second ARIN meeting I have participated in.

On the second day of the meeting, John Curran gave a presentation on Government Affairs and Public Policy (slides). In this presentation he spoke about a meeting of Internet coordinating bodies he attended in Uruguay earlier this month. In this meeting, those assembled "called for the transition to IPv6 to remain a top priority globally. In particular Internet content providers must serve content with both IPv4 and IPv6 services, in order to be fully reachable on the global Internet."

This statement grabbed my attention. During the open microphone following his presentation, I posed the following question: "What can we do to encourage the content providers to step up their adoption?" This was his response:
"It's actually not that hard. If someone says they have something on the Internet and it's not v6 reachable, call them on it. It's only on a subset of the Internet. If you have a website and it's not v6 reachable, it's not on the Internet. It's only on a part of the Internet. If everyone in this room says that to everyone they meet, that will make a difference."
For years many have been debating the chicken-and-egg scenario of which end needs IPv6 first: content or access? Of course the right answer is both, but many are reticent to be first movers. We have now reached a point where the content providers must step up to prevent a new NAT nightmare. Access providers are running out of IPv4 space. They are going to start needing to upgrade their equipment in order to continue to provide services to their users. If the primary source of the content those users are accessing is still IPv4 only, they will likely opt for Carrier Grade NAT (CGN) in lieu of upgrading directly to capable equipment. This is not a viable solution. NAT was originally created to give the Internet community time to perform the migration to IPv6. That time is about up.

If you are trying to enable your site to deliver content over IPv6 and having problems, let us know.

Learn (or Review) IPv6 Troubleshooting!

If you missed my first LinuxFest talk on IPv6 Troubleshooting, you have a second chance! I will be speaking on Saturday at Ohio LinuxFest 2013 too. I think the LinuxFests want me to get out of the office to meet the community, and I'm really looking forward to it!

Graph from SELF 2013

Who doesn't like pretty graphs?

I didn't think to go back and grab the graph until Sunday morning, but this gives you a sense of how much traffic we passed through the lab in the afternoon on Saturday.

The wireless coverage in parts of the main exhibit hall was a bit spotty, so our access point was filling in some gaps.

Learn IPv6 Troubleshooting!

Someone around here tried to convince me to go to Southeast Linux Fest 2013. Without thinking about the consequences, I replied truthfully. I said I much prefer to go to conferences when I'm speaking. Other attendees, after learning some of my strengths, ask me questions, so I'm involved in more conversations that are often quite lively. I enjoy public speaking, and I definitely air my opinions! It does put me in the spotlight, but I get a lot more (both information and fun!) out of the conference if I present.

You do see where this is going, right?

Yes, despite having never been to SELF before, I will be speaking at SELF 2013 on IPv6 Troubleshooting. I've watched some of the videos from previous years (suggestion) to get a feel for it, and I'm excited! The draft schedule is on the Southeast Linux Fest site already, and (for now) I'm speaking Saturday at 4 PM in the Digium room. Please come join the fun!

SouthEast LinuxFest 2013

Join us at SouthEast LinuxFest for an interactive network lab experience. You are encouraged to:
  • Bring your network enabled computer, smartphone, tablet, toaster, etc. to see how it works on an IPv6 network.
  • Bring your router to get configured for IPv6 connectivity. 
Experienced IPv6 enthusiasts will be on hand to answer your questions and work with you to generate ideas on how to deploy in your environment.

IPv6: It's not new, it's now.

Hello World!
