Telstra Rolls Out IPv6 To Business ADSL Customers
We were very pleased to learn (via ZDNet) that Australia’s largest telecommunications company, Telstra, has just rolled out IPv6 connectivity to all of its business ADSL customers. Using a dual-stack approach of allowing both IPv4 and IPv6 connectivity, Telstra’s David Robertson said in their news release:
“As stocks of IPv4 addresses diminish globally, we need to continue moving to the new addressing system. By dual stacking IPv4 and IPv6 in our network, customers can opt into IPv6 in their own time, and according to the lifecycle upgrade of their own equipment. We’re developing the network capability so customers can commence the move to IPv6 as it suits them.”
and noted that they expect to move to a position of always supplying IPv6:
“In coming years we expect that IPv6 will become the norm and customers will need to opt-out if they wish to use IPv4.”
It’s great to see Telstra enabling Australian businesses to use IPv6 and congrats to their technical team for making it all happen.

Video: IP-Spoofing / Routing Best Practices Panel at RIPE 66
Can we stop the spoofing of IP addresses? Is the problem serious enough to warrant high-level attention? Are there best practices for routing that the larger community should be engaging in? What are the real challenges with stopping IP spoofing? These are the questions addressed in a recent post by our colleague Andrei Robachevsky, “Can we stop IP-spoofing in the Internet?” and a corresponding panel at the RIPE 66 event in Dublin, Ireland, in mid-May.
If you are are interested in this topic of how we increase the security and resiliency of routing, we highly recommend both reading Andrei’s article and listening to the panel presentation from Dublin. (Click on the image below to go to the RIPE66 page where you can view the video.)
Slides are also available but they were primarily used to frame the introduction to the panel. The real content is in the panel discussion itself.
Please visit our new Routing Resiliency/Security area to learn more about this general topic of how to make the Internet’s routing infrastructure more resilient and secure.

Missed The VUC Hangout About DNSSEC and VoIP? Watch The Recording…
Interested in learning more about how DNSSEC can potentially work with VoIP? If you missed the VoIP Users Conference (VUC) Hangout in Google+ back on May 3 where I discussed this topic, you can now watch the archive at:
It was a very enjoyable presentation and I do thank VUC host Randy Resnick for having me on the show.
I’ll note that I also have posted a set of slides about DNSSEC and VoIP, and we’ve now set up a “DNSSEC and IP Communications” page here on Deploy360 where we will continue to add resources as we become aware of them.

Next “SIP Over IPv6″ Task Group Call On Thursday, June 20,
For those interested in helping make Voice-over-IP (VoIP) work over IPv6, and specifically VoIP using the Session Initiation Protocol (SIP), the next conference call of the SIP Forum’s “SIP Over IPv6″ Task Group happens tomorrow, Thursday, June 20, 2013, at:
19:00 Central European Summer Time
18:00 British Summer Time
13:00 US Eastern Daylight Time
10:00 US Pacific Daylight Time
The dial-in number will be +1 972 756 9798 with a conference PIN of 009444. Additional country-specific dial-in numbers can be found in the email announcement.
In the agenda announcement from Rifaat Shekh-Yusef the items to be discussed include:
1. draft-klatsky-dispatch-ipv6-impact-ipv4
- Discuss the feedback and how to continue the discussion on the DISPATCH mailing list
- *Talk about the options for moving the document forward (AD sponsor vs. new WG)
2. Discuss the text for two new sections that Mohamed Boucadair provided.
(See “IPv6 Implementation Guidelines” & “IPv6/IPv4 Interworking Function: Avoid IPv6 address Leakage?” in the attached document)
- Should these be added to this draft, which means that we are extending the scope of this draft? or
- Should we create a separate draft?
3. Happy Eyeballs
4. Sunset4 WG
We received an email of interest from Marc Blanchet, co-chair of sunset4 wg, stating that this work is relevant to the work they are chartered to do.
Marc suggested that we socialize this work with the sunset4 wg, which I did already. He also suggested that we present this work during the coming IETF in Berlin.
We’re delighted to see this ongoing work within the SIP Forum and that several documents are now under consideration. We do encourage anyone interested in helping SIP work over IPv6 to participate in this call and to join the SIP Forum “IPv6″ mailing list for this task group.
For more information about VoIP / SIP and IPv6, please see our page on IPv6 and IP Communications.

With Our Every Action, We Create The Kind Of World We Want To Live In

Build people up - or tear people down. Your choice.
I have been reminded of this several times lately in choices I have been confronted with. One stark moment was a few weeks back when we here in New England were being hit by an incredibly unseasonably cold spell. On Facebook, my newsfeed was full of friends in the region complaining about having to turn their heat on, about how strange this was, etc.
Now, a couple of friends of mine in the region maintain a fairly constant stream of political posts on Facebook and have a rather hardline conservative view of the world. Their posts are full of extremely negative text and links about President Obama, Congress, Democrats, "liberals" and pretty much anyone else that doesn't fit their worldview... usually delivered with a VERY heavy degree of sarcasm and anger.
They take it to such extremes that I often do find it hard to read their posts, but I haven't "hidden" their feeds on Facebook primarily because I don't want to be stuck in a self-affirming "echo chamber" of views like mine. I keep their posts coming because I want to be reminded of the many divergent views we have... but that's a good topic for a different blog post...
Anyway, one of these friends wrote on Facebook about how unseasonably cold it was and just expressed his surprise at having to turn the heat on at this time of year.
My immediate reaction was to click in the comment field and start typing the snarky reply:
What? You haven't figured out how to blame Obama yet?
And then I paused before hitting return and publishing the comment.
Just a few days prior to this I'd been having a couple of different discussions with people about the divisiveness within our society, the lack of civility, the way that sides within our political world here in the US seem to be getting more deeply entrenched ... and just about how there seemed to be acrimony and negativity online.
And here I was... about to add to that.
I deleted the text and cancelled adding the comment.
Sure, the comment would have been "fun". I would have enjoyed leaving it. It would have been enjoyable to poke a little bit at the fact that yes, indeed, some things out there are beyond the control of even your bitterest enemies.
But was it really necessary?
Here was a friend writing about his current condition. No politics. No name-calling. Just stating how things were.
I could have been empathetic / compassionate and joined him in commenting on the strange weather. Or I could have done what I was about to do and get a dig in (where there wasn't one) and add to the divisiveness.
Build people up - or tear people down.
A day or so later I saw on Facebook a graphic circulating that attributed to Sufism three questions to think about before speaking or writing something:
1. Is it true?
2. Is it necessary?
3. Is it kind?
I haven't been able to find a definitive source for these questions - the closest seems to be these sources in a Daily Kos article - but regardless of origin, the questions are good ones. And in this particular case my proposed writing failed #2 and #3 in a big way.
The good news is that I did pause, reflect, and pulled back from that instant response.
That time.
Now, to be honest, in another recent case I did send an email response I probably shouldn't have and while it was true and perhaps necessary, it wasn't really kind.
Every moment. Every action.
Build people up... or tear people down.
The choice we make, in each moment, defines the kind of world we want to live in.
Your choice...
P.S. For those curious, the photo is one I took of "Eartha", a giant globe at the DeLorme headquarters store in Yarmouth, Maine.

Video: Great WebRTC Tutorial and Demonstrations by Cullen Jennings
The presentation is about an hour and is followed by a question period. Well worth watching if you want to understand the current state of WebRTC and how it may impact telecommunications today.
Note, you can also view the video directly on YouTube to better see it in a larger size or on a mobile device.
P.S. For more information about WebRTC, see the links off of my WebRTC/RTCWEB page.
