Tunnel vision is a rather serious medical condition and the Internet or at least a number of service providers could be at risk if not treated soon enough. Symptoms of inter AS (Autonomous System) tunnel vision are many slower connections with IPv6 compared to IPv4 with some failing all together. Reason is that tunnels, especially inter-AS tunnels, can lead to long paths and non-optimal routing. more
We don't give enough credit to people who will sacrifice themselves trying to plug the IPv4 dam with some NAT-putty. They even dream of a NAT66 filled afterlife. The growing IPv6 traffic trickle was given evidence at the recent RIPE 57 meeting in Dubai in a number of presentations, including a most edifying Google presentation. Noteworthy to see France with a 0.65% IPv6 penetration... more
As we continue our ride toward the exhaustion of IPv4 addresses, Regional Internet Registries public discussion groups remain filled with endless discussions on how large swaths of allocated IPv4 addresses are unused, should be reclaimed or recycled one way or another, maybe be put on the free market and sold to the highest bidder or parsed out in more egalitarian controlled ways. Although everyone now accepts the notion of IPv4 address exhaustion, it seems to be for some an invisible glass wall and for others a gold brick wall worth the death of the internet to get a piece of it. more
IPv6 is in the news because the mainstream media have started to pick up the fact that IPv4 will be fully allocated in the next two or three years. And IPv6 deployment is important if we want to keep the Internet growing sustainably. So where is IPv6 deployment most evident? more
resentations at successive IPv6 related forums, summits and other conferences tend to become rather repetitive and some even in need of an urgent slide dust-off. Luckily some fresh perspectives emerge occasionally such as at the Taiwan IPv6 Summit early September. Being in the market for a new home router, I could not but pay attention to a presentation by D-Link extolling their IPv6 support for home routers! more
With the thousands of IPv6 controlled lights dimming over the 2008 Olympics, the long march on the road to IPv6 continues as the Olympic IPv6 Workout enters history. The early objective of full commercial deployment for 2008 proved elusive and more realistic goals were set and met with success. Not wasting any time, the starting shot toward commercial deployment followed on the heels of the closing ceremony with the august 25th announcement... more
Some think IPv6 with its myriad addresses will accelerate the evolution of a hyperconnected world. But could a world where everything and everybody is sensed, monitored, located, to augment our quasi real-time interaction with the world outside our little selves, lead to total dependency, if not to gradual stupidity of the human race? Not surprisingly, a favourite topic for (late night) Internet Conference bar discussions... more
During the last decade, the Internet Engineering Task Force (IETF) has been designing IPv6 as a replacement for IPv4. Most of the initial benefits of IPv6 (security, QoS, autoconfiguration,...) have been ported to IPv4 and IPv6 deployment has been limited. However, thanks to the huge IPv6 addressing space, it is possible to design protocols and mechanisms that are more scalable and more powerful than with IPv4. A typical example is the multihoming problem. This problem occurs when a site is attached to several Internet Service providers... more
Both the Internet and North American cellphones are choking under a 32 bit limitation and reactions from protagonists involved in both cases offer striking similarities. 1983 saw the debut of IPv4 and North American mobile telephony started in earnest with Bell's analog AMPS (Advanced Mobile Phone Service). Responding to the need to uniquely identify the growing number of mobile devices in order to bill their owner, the FCC ordered that handsets be equipped with a unique identification number embedded on a chip. This became the 32 bit ESN... more
IPv6 is "critical to achieve our net-centric vision", said Kris Strance, DoD Lead for IP Policy, speaking at the Information Assurance Collaboration Forum (IACF) in Laurel, Maryland last week. The Defense Department sees the proliferation of IP-addressable devices as a key driver for IPv6 adoption, and does not believe that IPv4 can satisfy its future requirements. The imminent explosion of non-traditional IP-enabled devices that Defense intends to implement may even threaten the large IPv4 address allocations that the Department holds. more
Is IPv6 a hot topic again in the wake of the increased coverage of the looming IPv4 address depletion? This was the theme of a coffee break discussion we had at the recent MENOG3 conference in Kuwait. With as many opinions as participants, I turned to "Google Trend" to help me get a better feel... Using IPv6 as search word and varying the time line indeed provided some interesting perspective and tidbits on when and where IPv6 seems to be or have been a hot topic indeed. more
One of the major principles of the architecture of the Internet was encapsulated in a paper by Saltzer, Reed and Clark, "End-to-End Arguments in System Design". This paper, originally published in 1981, encapsulated very clearly the looming tension between the network and the application: "The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the end points of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible." At the time this end-to-end argument was akin to networking heresy! more
The Cooperative Association for Internet Data Analysis (CAIDA) and the American Registry for Internet Numbers (ARIN) presented the results [PDF] of a recent IPv6 survey at the ARIN XXI Public Policy Meeting in Denver on April 7th. The survey involved over 200 respondents from a blend of Government, commercial organizations (including ISPs and end users), educational institutions, associations, and other profit and non-profit entities. The purpose of the survey, conducted between March 10th and 24th, was to capture IPv6 penetration data in the ARIN region... more
"The world is flattening," says Dave Rubal at the FOSE Conference and Exhibition this week in Washington, DC. "The race for IT dominance is on, and it is coming west." Mr. Rubal, Cisco's Worldwide Internet Protocol version 6 (IPv6) Task Force Lead, spoke of the tremendous race in IT dominance that is occurring, stating that the "mainstay technologies at the Beijing Olympics will be IPv6-powered." IPv6 is in line to replace version 4, but Rubal hinted that China and other Far East countries may be adopting the new version faster than the United States... more
The Internet Architecture Board's (IAB) chair, Olaf Kolkman, asked the members of the IAB to provide a statement paper each on what they believe the current most pressing issues in terms of Internet architecture are... I have thought about this for the past few days, and realised that it's hard to come up with overarching issues and even harder to come up with issues, where the IAB actually could make a difference. But I came with up with two issues. more
