Now that IPv6 deployment is happening in major networks around the world, the question becomes -- what does "success" look like for IPv6? How much IPv6 traffic is "enough"? What are major milestones we should be tracking in IPv6 deployment? What is next for IPv6? more
This weekend brought the great news that Google's IPv6 statistics have shown that connections over IPv6 to Google's web sites hit the 2% threshold for the first time. (You can see for yourself.) While 2% sounds tiny, as I wrote in a Deploy360 post today, the important fact here is that this represents a doubling of IPv6 traffic to Google over the past year! more
Ever want to know where all the submarine cables are that provide part of the physical infrastructure of the Internet? Or which cities in the world have the most connectivity via submarine cables? (or which regions might be single points of failure?) In doing some research I stumbled across this excellent site from the folks at TeleGeography... It is a very well done and captivating (to me, anyway) view into where all the current and planned submarine cables are located. more
One of the most prominent denial of service attacks in recent months was one that occurred in March 2013 between Cloudflare and Spamhaus... How did the attackers generate such massive volumes of attack traffic? The answer lies in the Domain Name System (DNS). The attackers asked about domain names, and the DNS system answered. Something we all do all of the time of the Internet. So how can a conventional activity of translating a domain name into an IP address be turned into a massive attack? more
When the domain name system (DNS) was first designed, security was an afterthought. Threats simply weren't a consideration at a time when merely carrying out a function - routing Internet users to websites - was the core objective. As the weaknesses of the protocol became evident, engineers began to apply a patchwork of fixes. After several decades, it is now apparent that this reactive approach to DNS security has caused some unintended consequences and challenges. more
The 87th meeting of the Internet Engineering Task Force (IETF) in Berlin, Germany, concluded on August 2, 2013. IETF Chair Jari Arkko recently published his summary of IETF 87 on the IETF Blog highlighting what he felt were some of the more important aspects of what was a very successful IETF meeting. I also had the privilege of interviewing Jari on video about the meeting. more
Can we create a "secure Caller ID" for IP-based communications, a.k.a. voice-over-IP (VoIP)? And specifically for VoIP based on the Session Initiation Protocol (SIP)? Can we create a way to securely identify the origin of a call that can be used to combat robocalling, phishing and telephony denial-of-service (TDOS) attacks? That is the challenge to be undertaken by the "Secure Telephone Identity Revisited (STIR)" group meeting tomorrow morning, July 30, 2013, at 9:00 am in Berlin, Germany, as part of the 87th meeting of the Internet Engineering Task Force (IETF). more
What makes the Opus codec so interesting? Why is there such a buzz about Opus right now? If you are not in telecom or doing anything with audio, why should you even remotely care about Opus? In a word... Innovation! And because Opus has the potential to let us communicate with each other across the Internet with a richer and more natural sound. You will be able to hear people or music or presenters with much more clarity and more like you are right there with them. more
Do "smart" parking meters really need phone numbers? Does every "smart meter" installed by electric utilities need a telephone number? Does every new car with a built-in navigation system need a phone number? Does every Amazon Kindle (and similar e-readers) really need its own phone number? In the absence of an alternative identifier, the answer seems to be a resounding "yes" to all of the above. more
I recently attended RIPE 66 where Tore Anderson presented his suggested policy change 2013-03, "No Need -- Post-Depletion Reality Adjustment and Cleanup." In his presentation, Tore suggested that this policy proposal was primarily aimed at removing the requirement to complete the form(s) used to document need. There was a significant amount of discussion around bureaucracy, convenience, and "liking" (or not) the process of demonstrating need. Laziness has never been a compelling argument for me and this is no exception. more
