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
In this article we'd like to look at some measures of the use of IPv4 and IPv6 protocols in today's Internet and see if we can draw any conclusions about just how far down the track we are with the IPv6 part of dual stack deployment. We'll use a number of measurements that have been made consistently since 1 January 2004 to the present, where we can distinguish between the relative levels of IPv4 and IPv6 use in various ways. more
We saw it in San Jose, then in Taipei and in Philadelphia and now it is about to happen in Denver Colorado! Yes, the IPv6 hour is about to occur a fourth and even a fifth time! The upcoming ARIN XXI will have a pre-game and a main event IPv6 hour with technical staff to assist the neophytes on their first dive into the IPv6 only world... In the meantime in the Geneva Auto show, impact of IPv6 on ITS (Intelligent Transport Systems/Services) was a topic on its own with a revealing and well timed presentation by Thierry Ernst of Inria, the French Institute of Research in Informatics and Automation. more
Video recordings of Google's IPv6 conference held on January 29, 2008 have been posted on YouTube. The conference was part of Google Tech Talks and includes a panel discussion called "What will the IPv6 Internet look like?" See first video... more
Day two of Domain Pulse 2008 last Friday (see review of day one) focused on online security issues giving the techies amongst us details of security issues, and the more policy-orientated amongst us something to chew on in a few other presentations. Kieren McCarthy, these days of ICANN, also gave some insights into the drawn out sex.com drama with more twists and turns than the average soap opera has in a year! And Randy Bush outlined the problems with IPv6. Among other presentations... more
Around 350 attendees came from Russia in the east to Ireland in the west, as well as a few people from elsewhere around the globe, to attend Domain Pulse 2008 in Vienna on February 21 and 22. Day one's focus was internet governance. The future of the DNS was one of the key issues addressed by Michael Nelson of Georgetown University in Washington DC, with domain names becoming less important, but their numbers still increasing, as online access by a myriad of devices skyrockets connect -- everything from the television, refrigerator, washing machine, pets, sprinkler systems and cars. more
The National Institute for Standards and Technology (NIST) has released a second draft of a proposed standards profile to support the implementation of IPv6 by government agencies. "NIST developed the 'profile' to help ensure that IPv6-enabled federal information systems are interoperable, secure and able to co-exist with the current IPv4 systems." ...The White House's Office of Management and Budget declared in 2005 that all federal agencies shall migrated to IPv6 by June 30, 2008... more
February 4th 2008 will be the day the repotting of the internet finally starts. A milestone of sorts for some people who spent a good part of the last five years getting us this far. It should now be finally possible for a IPv6 only device to have a chance to communicate on the Internet. Indeed, today, IPv6 address information is not included in most root DNS servers. Some good write-ups are already appearing on the subject covering the relevance of this development... Why get excited as there are practically no IPv6 only devices yet, some will bemoan. Well, one can hear a distant rumbling of such devices coming, alongside the mobile internet... more
Wide-Area Data Services (WDS), aka "WAN Optimization" is becoming the most effective way to improve application performance while reducing network traffic. In scenarios where there is significant network latency that would otherwise render many applications unusable, WDS can deliver almost LAN-like speed. Where bandwidth constraints exist and there is no practical or economical option, WDS can help reduce network traffic, allowing you to postpone or avoid circuit upgrades altogether. The technology provides the ability to centralize applications and servers, furthering the cost savings on hardware, software licensing, maintenance and the operation of a distributed architecture. more
