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»

Is It Time to Create a Market for IPv4 Addresses?

It's fascinating to watch the Internet technical community grapple with policy economics as they face the problems creating by the growing scarcity of IPv4 addresses. The Internet Governance Project (IGP) is analyzing the innovative policies that ARIN, RIPE and APNIC are considering as a response to the depletion of IPv4 addresses. 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»

IPv6 and Airline Tickets… Tales of Two Transitions

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... 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»

Important New Jersey Supreme Court Decision in Internet Privacy

The New Jersey Supreme Court has issued an important decision on Internet users' right to privacy. The case involves a dispute about whether an ISP violated a user's privacy rights by turning over subscriber information (name, address, billing details) associated with a particular IP address. It ends up that the subpoena served on the ISP was invalid for a variety of reasons. As the user had a 'reasonable expectation of privacy' in her Internet activities and identifying information, and because the subpoena served on the ISP was invalid, the New Jersey court determined that the ISP should not have turned over the personal data... 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»
