Internet Bigger Than Agriculture or Energy Sectors - Importance of R&E Networks

Several months ago McKinsey did a very interesting study on the economic value of the Internet. They pointed out that Internet in the G8 countries as well as Brazil, China, India, South Korea, and Sweden is now bigger than agriculture or energy. The Internet represents 3.4% of GDP and accounted for 21 percent of GDP growth over the last five years among these developed countries and as Vint Cerf pointed out in his blog created 2.6 jobs for every one lost. more

U.S. Government Strongly Affirms ICANN Model and New gTLDs

Larry Strickling, who runs the NTIA (the part of the U.S. Department of Commerce that handles ICANN), yesterday gave an important and remarkable speech to the Practicing Law Institute about Internet governance. His speech, timed to coincide with an orchestrated ICANN-bashing across town in the Senate, was a striking defense of the ICANN model and a repudiation of special pleading outside the process. more

Senate and House Hearings on New Top Level Domains Not Likely to Delay Launch

Yesterday, the US Senate Committee on Commerce, Science and Transportation held hearings on ICANN's expansion of top level domains. Next week the House Energy and Commerce committee will also conduct their hearings on this same topic. more

Greylisting Still Works - Part II

In my last post I blogged about greylisting, a well-known anti-spam technique for rejecting spam sent by botnets. When a mail server receives a an attempt to deliver mail from an IP address that's never sent mail before, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail senders always retry, badly written spamware often doesn't. I found that even though everyone knows about greylisting, about 2/3 of IPs don't successfully retry. more

Greylisting Still Works - Part I

Greylisting is a hoary technique for rejecting spam sent by botnets and other poorly written spamware. When a mail server receives an attempt to deliver mail from a hitherto unseen sending host IP address, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail software does try again, at which point you note that the host knows how to retry and you don't greylist mail from that IP again. more

Online Property Protection and the Public Interest

Proposals to enhance online property protection have received a lot of attention lately. Brand managers, goods manufacturers, and content distributors strenuously argue that current law enforcement mechanisms are inadequate to meet the challenges of today's fast-paced marketplace. They specifically note that foreign-based "rogue websites" continue to distribute unlicensed products and content despite existing rules; they maintain that new legislation is needed to empower intellectual rights holders to counter such cyber-criminals more effectively. more

Security, Privacy Issues and USB Drives

In an article on CSO.com.au a report from Sophos Australia is reported on. The anti-virus software company had bought 50 usb drives for analyses at a public transport auction of devices left on the Sydney trains. When they wrote that 66% was infected with malware, I presumed that they were left behind consciously, but were they? more

Beyond Words: Diverse Voices at ICANN and Miscommunications

A few days ago, I sat in a meeting here in Ottawa with our IT Director and Director of Marketing and Communications. These are two highly intelligent people working on the same team, for the same company, talking about a common subject. And yet, something was amiss in achieving mutual understanding. Each was seeing things from his own distinct perspective and as such, speaking his own language. As I reflected on my team's internal dynamic, I began to see parallels in areas that have an even more direct impact on the Internet ecosystem. more

Dealing With the Digital Divide

A political focus on subsidizing telecom infrastructure is just so easy. There are multiple photo opportunities (at the announcement, the cheque presentation and the system activation), happy mayors, happy voters. It gets to be portrayed as economic stimulus, direct job creation and consistent with progress on digital economic development. But while it may feel satisfying politically, I question the effectiveness of continued broad government subsidies based on geography, rather than taking a more focused approach based on need. more

SOPA Could Shutter Registrars and other Domain Name Industry Intermediaries

The Internet Commerce Association has just sent a letter to senior members of the House Judiciary Committee regarding the likely unintended but potentially devastating impact of H.R. 3261 ("SOPA") as introduced upon ICANN-accredited registrars and other participants in the broad domain name industry, as well as upon the domain registrants who use those services. more

Borders, In Bankruptcy, Aims To Sell 65,536 IPv4 Addresses at $12/Address

With IPv4 address exhaustion upon us, it appears that the going market rate for IPv4 addresses is now $12/address. Over at the Register, Kevin Murphy reports on a bankruptcy filing from Borders seeking to sell a /16 block of to healthcare software vendor Cerner for a total of $786,432. At $12 per IPv4 address, this sets a new public record given that the previous high was Microsoft's acquisition of a block of Nortel IPv4 addresses... more

Data Tsunami and the Looming Broadband Capacity Crisis

There is such a huge volume of genomics (DNA related data) and bio-informatics data being produced that it cannot be transferred over commercial Internet networks, and instead organizations are using FedX and other sneaker nets to ship the data. The same crisis in data volumes is also occurring in the climate modelling and other fields as well. Research and Education (R&E) networks for many years have been warning about this coming data tsunami. more

DNS Measurements with RIPE Atlas Data

As described in New RIPE Atlas Features in the Making, each RIPE Atlas probe performs "anycast instance discovery" measurements. This means, for each DNS root name server, we determine which instance of a name server a probe uses. We compile the data from all probes and build maps showing these results for each Atlas probe. In other words, the map shows the "gravitational radius" for root DNS server instances. more

FCC to Hold Two December Workshops on PSTN Transition to New Technologies

The US Federal Communications Commission (FCC) recently issued a public notice that it will be holding two workshops on the transition of the public switched telephone network (PSTN) to "new technologies" such as voice-over-IP (VoIP). The workshops will be held on December 6 and 14, 2011, at the FCC's office in Washington, DC. The public notice states the goal as... more

The Death of TLD Front Running

In an article published over two years ago, I cited a disturbing trend of third parties seeking to obtain national trademark registrations in an apparent attempt to game ICANN's new gTLD process. While many of these applications have withered and died on the vine some have sneaked through. However, it appears that the United States Trademark Trial and Appeal Board (TTAB) has issued a very well-reasoned and articulate opinion... more
