The IPv6 Inconvenient Truth: Deployment Could Cause Network Problems, Threaten Cybersecurity

The move to Internet Protocol version 6 (IPv6) could have a profound affect on the Internet, breaking it up into islands of connectivity and threatening cybersecurity in the process, according to Jeff Young, a senior analyst at the Burton Group. As the IPv4 free address pool continues to dwindle, enterprises can expect to see IPv6-only hosts on the Internet within a three-year timeframe, Young said. In the report, "IPv4 Address Exhaustion: An Inconvenient Truth," Young addresses the incompatibility of IPv4 and IPv6 and some of the problems that need to be addressed during the changeover. more

Geoff Huston on Securing the Internet Routing System

Excerpts of a recent interview by Network World's Carolyn Duffy Marsan with Geoff Huston, one of the foremost authorities on Internet routing and scaling issues, has been published on the site. Questions include: "Can you explain in plain English what RPKI is trying to do and how it relates to improving the security of the Internet's routing system?" Huston's response follows... 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

Feds Ready for IPv6 D-Day

On June 30, U.S. federal government officials expect to declare an early victory on the IPv6 front. But they admit that meeting their much-heralded June 30 deadline for IPv6 compatibility is just the opening salvo of a long-term battle to get their networks ready for the Internet of the future. Under a White House policy issued in August 2005, all federal agencies must demonstrate the ability to pass IPv6 packets across their backbone networks by this deadline. more

Regional Internet Registries Appeal for IPv6 Investment at OECD Conference

Ministers from more than 40 countries are discussing the future of Internet economy at OECD meeting in Seol, Korea, 17-18 Jun. Discussions include security, competition, and strengthening the role of the Internet economy in enhancing social and economic development as well as agreement on new ways to improve global co-ordination and co-operation. The Number Resource Organization (NRO) today issued an appeal for investment in IPv6 infrastructure. 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

Google Officially Announces Introduction of IPv6

Google search is available over IPv6 at ipv6.google.com (you'll need an IPv6 connection to view it)... From the official blog: "We hope that by allowing every computer and mobile device on the network to talk to each other directly -- an idea known as the "end-to-end principle" that was crucial to the original design of the Internet -- IPv6 will allow the continued growth of the Internet and enable new applications yet to be invented." more

IPv4 Shortage and Trading Concerns as Hot Marketable Goods

With IPv4 addresses in short supply, they could become increasingly interesting and marketable goods. This is a concern for Regional Internet Registries (RIR) that are in charge of managing IP address allocations. Heise Online reports: "If they officially permit transfers or sales in the future, they will be implicitly accepting commercialization and privatization. Any attempt to insist on the return of addresses to the RIRs could drive trading, which is probably inevitable, underground..." more

Significant Chunk of IP Address Space Hijacked by Notorious Mass Emailing Company

Internet address space long ago issued to San Francisco Bay Packet Radio, an organization that was involved way back in the 1970s in testing ARPANET, a predecessor to the global commercial Internet that we all use today. That organization was given the rights to do whatever it wanted with 134.17.0.0/16 address block. That entire swath of Internet space is now registered to an entity in Westminster, Colo., called SF Bay Packet Radio LLC, but except for a similar name, this company has no relation to San Francisco Bay Packet Radio... ? 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
