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.
The internet bus continues to accelerate straight into the IPv4 address depletion wall with spirited discussions continuing on how to divvy up the remnants of the address space. Obviously all five Regional Internet Registries (RIR's) want to make sure they get their fair share from IANA but what is a fair share remains the subject of interpretation. In the mean time, scenarios of a speculative land rush and auctions of ever smaller address blocks abound with unattractive consequences such as an explosion of the size of the routing table and a stunted growth of the global internet economy... In the meantime, the airline industry completed a rather significant migration of their own...
The European Commission has released a communication on IPv6, in time for the IPv6 Day in Brussels next 30th May. It goes in the same direction as the report presented at the OECD Ministerial meeting on "Future of the Internet Economy", that was held in Seoul, Korea earlier this month. At the same time, the Commission committed to make its own web services available on IPv6 by 2010. It is good to see that intergovermental organizations take the lead on this, after 10 years of failure of the private sector to actually deploy IPv6...
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.
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!
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...
"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...
Now that ICANN has added IPv6 name servers for the root zone, and that many registries have enabled IPv6 on their DNS servers, I thought it would have been easy to update the DNS records pointing to my domain to mention a IPv6-only DNS server. This way, we could have native name resolution end-to-end in IPv6. We are not there yet, it seems.
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.
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.
