Comments? Olle’s Thoughts on SIP (VoIP) and DNSSEC / DANE

How you you think DNSSEC and specifically DANE could be used with the Session Initiation Protocol (SIP) to provide an added layer of security to voice / video communications over IP? (a.k.a. “VoIP”)   I started raising this question back in a presentation at SIPNOC 2013 and again in a recent VUC interview about DNSSEC and VoIP, but today to my delight Olle Johansson dove a bit deeper with a set of slides about SIP and DNSSEC / DANE he posted up on SlideShare. These are just his “brainstorming” a bit about how DNSSEC/DANE could work with SIP – and he has posted them for comment and feedback:

I like that he went deeper than I had done into precisely where in the SIP interactions DNSSEC / DANE could play a role.  Olle is definitely looking for comment which you can leave in many different places (such as SlideShare, this blog post, anywhere it’s posted on social networks) or can send directly to Olle or send out on the DANE working group mailing list.

I’m pleased to see the continued evolution of this discussion… and I look forward to seeing more work happen in this space.  (Note that I’ve set up a page here about DNSSEC and VoIP to track where some of this work is happening (and am always looking for items to add).)

TDYR #019 – On The Need For Time Offline – And Time For Reflection

In the fast-paced, always-on world of today, how do we carve out time when we disconnect and reflect on how pieces fit together? Do we need to go completely offline, as Baratunde Thurston recently did for 25 days? Do we need to schedule in some time in our regular week? (Or do we not need to?) What do you find works for you?

4 Outstanding IPv6 Transition Videos From RIPE NCC

Want to understand what various IPv6 transition mechanisms are available to help you with the move to IPv6?  Interested in understanding the differences between “6in4″, “6RD”, “NAT64″ and “DS-Lite”? (Or what they even are?)

If so, our friends over at the RIPE NCC have put together a set of four IPv6 transition videos that are excellent ways to learn about these technologies. Using animations, these videos provide easy explanations of what each transition mechanism is all about, what a service provider needs to think about and how to go about implementing each mechanism. Perhaps most importantly, the videos explain when you might want to use a certain technique.

IPv6 Transition Videos From RIPE NCC

 

The page for each video also includes links to relevant documents for people wishing to learn more.  The videos are also all out on YouTube which makes it easy for the videos to be shared or embedded in other websites.  They are also viewable on both desktop and mobile devices.

Kudos to the RIPE NCC Training team for creating these excellent videos and we hope they do help people understand what options are out there.  Let’s get out there deploying IPv6!

TDYR #018 – Happy Canada Day!

Today, July 1, is Canada Day, a national day of celebration in that country. In this brief episode I record a few brief thoughts about the five years we spent in Canada and the effect it has had on my life - and wish all Canadians a very happy Canada Day!

Telstra Rolls Out IPv6 To Business ADSL Customers

telstra-logoWe 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,

SIP ForumFor 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.
