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
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 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
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
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
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
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
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
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
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
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
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
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
While the global rollout of DNSSEC continues at the domain name registry level - with more than 25% of top-level domains now signed - the industry continues to focus on the problem of registrar, ISP and ultimately end-user adoption. At the ICANN meeting in Dakar in late October, engineers from some of the early-adopting registries gathered for their regular face-to-face discussion about how to break the "chicken or egg" problems of secure domain name deployment. more
The word gTLD has been added to the hardcore lexicon of global branding. Why is this new spin causing vertigo to some? Before you say anything else like 'what'? Just hold on. It makes no difference whether you already are an expert on gTLD or not. The fact is it's in your face and we all have to deal with it for a long time, so deal with it. On the internet today, from around the world, there are over 10,000 articles on ICANN's gTLD... more
