IPv6… the Internet Dragon Stirred Under Its Shell

At Cisco Networkers in Barcelona earlier this week, some of us saw a dragon try to wiggle out of its shell, provided you connected in IPv6 that is. A smile to Kame, the turtle which only danced under a IPv6 caress. Networkers 2009 saw more than 3000 attendants and a good complement of IPv6 presentations highlighted by a high powered plenary panel on the status of IPv6. more

Vint Cerf: 2009 a Turning Point for the Internet

Patrick Neighly reports on CommsDay about the Pacific Telecommunications Council 2009 Conference held last week where Vint Cerf was a keynote speaker. From the report: "Historians will view 2009 as a turning point in Internet history, according to Google internet evangelist Vint Cerf. Speaking to PTC'09 attendees, the legendary figure warned the industry to brace for 'significant change' and said Asia was poised to forever change the look and experience of the online landscape. The region boasts 578.5 million surfers with nearly 85% of its population still to come. That influx is likely to combine with the launch of non-Latin-character addresses to reshape the Web into a very different beast." more

Google Rolling Out Its Services Over IPv6

While Google admits that offering its services over IPv6 is still in its infancy, the company today announced the option for accessing Google services over IPv6. Last year, Google started offering Google search over IPv6 on IPv6-only websites like 'ipv6.google.com' requiring IPv6 connection, but other Google products have not been generally available over IPv6, says Google. "That's why we created Google over IPv6." more

IPv6… The Dangers of Prolonged Inter AS Tunnel Vision

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

IPv6… the Year NAT-Enforced IPv4 Dam Showed Seepage

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

IPv6: Zeno’s Paradox and Invisible Brick Walls

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

Remembering Jon: Looking Beyond the Decade

A decade has passed since Jon Postel left our midst. It seems timely to look back beyond that decade and to look forward beyond a decade hence. It seems ironic that a man who took special joy in natural surroundings, who hiked the Muir Trail and spent precious time in the high Sierras was also deeply involved in that most artificial of enterprises, the Internet. more

Which Region is Taking the Lead in IPv6 Deployment?

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

Defense Department Demonstrates Compliance with the OMB IPv6 Mandate

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

The End of End-to-End?

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

CAIDA and ARIN Release IPv6 Survey

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

NIST Releases a Profile for IPv6 in the U.S. Government for Comment - Comments Due Feb. 29

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

Internet Governance: The Issue, The Myths, The Problems, The Solutions

I have written a short paper on the topic of Internet Governance. Since it includes a number of resources, it would be easier for me to just point to a link with the document itself. Below are some selected excerpts from the document. "Several myths have been spreading around the World Summit on the Information Society (WSIS), but especially after the first Internet Governance Forum (IGF): The critical Internet resources (CIR) consist only of the IP addresses and the domain name system... There are only 13 root servers..." more

IPv4 Address Exhaustion and a Trading Market

There are discussions starting within the Regional Internet Registries (RIRs) about the creation of trading market in IPv4 addresses as we approach the inevitable exhaustion of unallocated addresses. The view being put forward is basically "this is likely to happen anyway and by discussing it now, we can ensure it happens in an orderly way". When I first heard this idea I was a bit surprised. The RIRs are policy based bodies and so a shift to a trading market appears to be an abandonment of that policy base. However I have been partly corrected on that. more

ARIN Statement on the Future of Addressing Policy

ARIN has just released a statement on the future of addressing policy. Specifically addressing the future of IPv4 addressing. What ARIN does is to emphasize the current policies and say they will be enforced even stronger than today if needed. I.e. there is no announcement of a change in policy. more
