IPv6 Key Part of Multi-Billion Dollar Smart Grid Projects

Carolyn Duffy Marsan of Network World writes: "Could Smart Grid, the Obama Administration's effort to modernize the nation's electric grid, be the killer app for IPv6? That's what Internet engineers are asking as they see billions of dollars in stimulus funds pumped into smart electric meters, automated utility substations and new sensors networks -- all of which could take advantage of the abundant address space and built-in security offered by IPv6, the long-anticipated upgrade to the Internet's main communications protocol..." more»

Root Scaling Study Report is Out

Earlier this year, ICANN began to seriously consider the various effects of adding DNS protocol features and new entries into the Root Zone. With the NTIA announcement that the Root Zone would be signed this year, a root scaling study team was formed to assess the scalability of the processes used to create and publish the Root Zone. Properly considered, this study should have lasted longer than the 120 days -- but the results suggest that scaling up the root zone is not without risk -- and these risks should be considered before "green-lighting" any significant changes to the root zone or its processes. I, for one, would be interested in any comments, observations, etc. (The caveats: This was, by most measures, a rush job. My spin: This is or should be a risk assessment tool.)

Annual Global IP Traffic Will Exceed Two-Third of a Zettabyte in 4 Years

Annual global IP traffic will pass two-thirds of a zettabyte in four years according the Cisco's Visual Networking Index report. The economic downturn has only slightly tempered traffic growth and the global IP traffic is expected to quintuple from 2008 to 2013. Cisco predicts IP traffic to grow at a compound annual growth rate (CAGR) of 40%. more»

Oracle Announces Agreement to Acquire Sun Microsystems

Brandon Bailey reporting on Mercury News: "In a surprising twist, Sun Microsystems announced this morning that it will be acquired by Oracle in a deal worth roughly $7.4 billion, or $5.6 billion net after accounting for Sun's cash and debt. The news comes just a few weeks after earlier talks for IBM to buy Sun [link] collapsed..." more»

Steve Crocker on the 40th Anniversary of RFC #1

Today marks the 40th anniversary of request for comments (RFC) documents that, as Steve Crocker who wrote the first RFC says, have shaped the inner workings of the Internet and have played a significant role in its success. In an op-ed in the New York Times today, Crocker writes: "When the R.F.C.'s were born, there wasn't a World Wide Web. Even by the end of 1969, there was just a rudimentary network linking four computers at four research centers: the University of California, Los Angeles; the Stanford Research Institute; the University of California, Santa Barbara; and the University of Utah in Salt Lake City. The government financed the network and the hundred or fewer computer scientists who used it. It was such a small community that we all got to know one another..." more»

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»

Finnish Security Researchers Decide to Go Public With a TCP/IP Flaw

Researchers at a Finnish security firm Outpost 24 claim to have discovered a flaw in the Internet Protocol that can disrupt any computer or server. After keeping the flaw quiet for years, the researchers hope that going public will help accelerate the creation of a solution, according to PC World Australia. The flaw enables attackers to bring computers and servers to a halt by sending a few specially formed TCP/IP packets. The result can be compared to a denial of service attack (DDoS), in which networks are flooded with traffic. However in this case only minimal amount of traffic is required. "We're talking 10 packets per second to take down one service," Jack Lewis, a senior researcher with Outpost24. more»

Internet's Biggest Security Hole

Kim Zetter reporting on Wired: Two security researchers have demonstrated a new technique to stealthily intercept internet traffic on a scale previously presumed to be unavailable to anyone outside of intelligence agencies like the National Security Agency. The tactic exploits the internet routing protocol BGP (Border Gateway Protocol) to let an attacker surreptitiously monitor unencrypted internet traffic anywhere in the world, and even modify it before it reaches its destination. more»

UK's Defense Group Warns Against Internet Protocol Security Challenges

Recent report says many textbooks and articles have created the myth that the Internet Protocols (IP) were designed for warfare environments, while in reality they originally focused on operational aspects of the protocol and overlooked security implications. United Kingdom's Centre for the Protection of National Infrastructure (CPNI) has released a document raising awareness of the many security threats from attacks based on the Internet protocol. more»

Manufacturers Urged to Upgrade Routers, Network Management Software Before End of Year

Regional Internet Registries (RIRs) have warned that routers and network management software should be upgraded ahead of the increased distribution of four-byte (also known as 32-bit) Autonomous System (AS) numbers. Geoff Huston, Chief Scientist at Asia Pacific Network Information Centre (APNIC - Asia and the Pacific region RIR), expressed severe concerns over failure to prepare for four-byte AS numbers... more»

Comcast Proposes Its IPv6 Transition Solution to IETF, Invites ISPs to Participate

Comcast, the largest cable operator in the U.S., is reported to have developed an innovative approach for gradually migrating its customers to IPv6. The company has 24.7 million cable customers, 14.1 million broadband customers and 5.2 million voice customers. The solution dubbed Dual-Stack Lite, is backwards compatible with IPv4 and can be deployed incrementally according the company. Comcast has submitted this proposal to the Internet standards body, Internet Engineering Task Force (IETF) which has scheduled a review during the upcoming IETF meeting in Dublin later this month. From the Comcast document submitted to IETF... more»

Pakistan Blocks Worldwide Access to YouTube

Pakistan's attempts to block access to YouTube have been blamed for a near global blackout of the site on Sunday. Google, the owner of YouTube, blamed the outage on "erroneous internet protocols", sourced in Pakistan. According to BBC News, the nearly two-hour long blackout was almost certainly connected to Pakistan Telecom and internet service provider PCCW.  more»

2008 Marking the 25th Anniversary of TCP/IP

Twenty five years ago, in January 1983, TCP/IP protocols replaced Network Control Program (NCP) as the principal protocol of the ARPANET making the Internet possible as we know it today. Vint Cerf and Robert Kahn have been credited for the invention of the technology... more»
