Live Today – “IPv4 Exhaustion and the Path to IPv6” from INET Denver (Featured Blog)

If you are interested in the current state of IPv4 address exhaustion within North America as well as the current state of IPv6 deployment, there will be a live stream today, April 17, of the sessions happening at INET Denver starting at 1:00pm US Mountain Daylight Time (UTC-6). The event is subtitled "IPv4 Exhaustion and the Path to IPv6" and you can view the live stream at. More...

Speaking at SIPNOC Next Week About IPv6 and DNSSEC With VoIP

SIPNOC 2013 logoInterested in how voice-over-IP (VoIP) can work with IPv6? Want to know how DNSSEC can add a layer of security to VoIP?  Next week I’ll be speaking on these precise topics at the SIP Network Operators Conference (SIPNOC) sponsored by the SIP Forum and happening in Herndon, Virginia.

SIPNOC is an excellent conference that I’ve very much enjoyed over the past few years that brings together many of the key players involved with moving our telecommunications infrastructure from its PSTN roots into the world of IP communications. Its target is operators and so you have a good number of people there who are providing VoIP services to customers – typically using the SIP protocol.  The schedule is always an interesting mix of operational best practices, security concerns, new technologies, policy and other topics.  This year it’s good to see WebRTC being on the agenda in several places, as that will have an effect on the overall VoIP infrastructure.  (FYI, there is still time to register to attend the SIPNOC event.)

As shown on the SIPNOC schedule, I’ll be participating in these sessions:


IPv6 And SIP – Myth or Reality?
Wednesday, April 24, 10:45-11:45am

In this session we’ll be exploring what is really going on with VoIP and IPv6 and seek to answer questions such as:

  • What’s going on with SIP over IPv6?
  • What are the main challenges to using SIP with IPv6?
  • What do we know about the status of current equipment working with IPv6?
  • What are the SIP Forum and others in the industry doing to help advance the state of the art?
  • Where do we see SIP and IPv6 going?

I’m very much looking forward to the session and have several panelists joining me in a discussion-style panel that should be quite educational and interesting.


Who are You Really Calling? How DNSSEC Can Help
Thursday, April 25, 9:30-10:00am

My goal with this session is to explain what DNSSEC is all about and to look at how it can potentially help to secure a few aspects of VoIP communication.  As I wrote in the abstract:

When Alice calls Bob, how does she know that she is really communicating with Bob’s SIP server? Sure, her software grabs a SRV record for Bob’s server from DNS, but how does Alice’s systems know whether that is the *correct* DNS record for Bob’s server? What if an attacker were able to inject DNS records that redirect Alice’s call to another system? What if there were a way that the SIP endpoints could be certain about the address of the other system they want to call?

I’ll also be talking about the Jitsi softphone that now supports DNSSEC as I wrote about in the past and more recently interviewed Emil Ivov, the Jitsi project lead.  I hope to get some people thinking about the possibility of using DNSSEC and looking into how it can work more with their VoIP infrastructure.


Beyond those sessions, I’ll also be engaging the “VoIP security” side of my background and moderating two sessions on Monday, April 23:

  • 5:15-6:15pm – Panel Discussion:  Anatomy of  a VoIP DMZ
  • 7:30-8:30pm – VoIP Security Birds-of-a-Feather (BOF)

The BOF, in particular, should be interesting as last year it was a very frank and open conversation between operators about the security issues they were facing.  Much good information – and solutions – were exchanged.

I’m very much looking forward to this event and if you are going to be at SIPNOC please do say hello.

At the current time the event is not being livestreamed, but I’m planning to record at least my sessions and make the video available through the Deploy360 YouTube channel.

Watch LIVE Today – INET Denver: IPv4 Exhaustion and the Path to IPv6

INET Denver logoWant to learn the current state of IPv4 address exhaustion and corresponding IPv6 deployment in North America?  Interested in learning about the state of the market for IPv4 addresses (i.e. the cost you may incur if you don’t move to IPv6)?  Want to learn what ARIN’s latest policies are around IP address allocation?

If so, you can watch the livestream of the INET Denver event happening today, April 17, starting at 1:00pm US Mountain time (3:00pm US Eastern, 12noon US Pacific) at:

http://www.internetsociety.org/events/inet-denver/inet-denver-livestream

The INET Denver agenda includes sessions on:

  • IPv4 Exhaustion Update
  • IPv4 Exhaustion at ARIN
  • Address Policy Workshop
  • Evaluation of Current Transfer Market
  • TCO of IPv6
  • Internet Society Initiatives and How To Get Involved

The event has an excellent set of speakers who are extremely knowledgeable in the field – it should be a great event!

Note that if you cannot view the event live, it will be recorded so that you can watch the sessions later.

As we mentioned previously, Richard Jimmerson and Jan Zorz from our Deploy360 team will be there and would be glad to meet with anyone there to talk about what we are doing here and to get feedback on how we can help get IPv6 deployed even faster.
