The Design of the Domain Name System, Part III - Name Structure and Delegation

In the previous installments, we looked at the overall design of the DNS and the way DNS name matching works. The DNS gains considerable administrative flexibility from its delegation structure. Each zone cut, the place in the DNS name tree where one set of DNS servers hands off to another, offers the option to delegate the administration of a part of the DNS at the delegation point. more

Spam Is on the Decline; What Are the Implications?

Previously, I wrote that the total amount of spam that we are seeing has seen a significant decline over the past year and a half. What does this mean in real terms? Are we finally winning the fight against spam? There are multiple angles. On the one hand, processing spam takes significant system resources... more

Protecting Yourself from Spear Phishing

One of the big trends this year is spear phishing. These are phish attacks that are frequently (though not always) against high profile users. The purpose of these attacks is to steal sensitive data or get elevation of privilege inside the service by exploiting a software vulnerability within the user's computer that transmits usernames and passwords back to the phisher. more

Underneath the Hood: Ownership vs. Stewardship of the Internet

As is well known to most CircleID readers - but importantly, not to most other Internet users - in March 2011, ICANN knowingly and purposefully embraced an unprecedented policy that will encourage filtering, blocking, and/or redirecting entire virtual neighborhoods, i.e., "top-level domains" (TLDs). Specifically, ICANN approved the creation of the ".XXX" suffix, intended for pornography websites. Although the owner of the new .XXX TLD deems a designated virtual enclave for morally controversial material to be socially beneficial for the Internet, this claim obfuscates the dangers such a policy creates under the hood. more

The Design of the Domain Name System, Part II - Exact and Approximate Name Matching

In the previous installment, we looked at the overall design of the DNS. Today we'll look at the ways it does and does not allow clients to look up data by name. The most important limitation of the DNS, compared to other databases, is that it only does exact match lookups. That is, with a few minor exceptions, the name in the query has to match the name of the desired records exactly. more

Washington Post: ICANN Departures After Web Suffix Vote Draws Criticism. How Damaged is ICANN?

ICANN Chairman and other departures after the board's vote to approve the New generic Top-Level Domains (gTLDs) in Singapore draw criticism, reports The Washington Post. Shortly after the vote, Peter Dengate Thrush joined a New gTLD Group which stands to greatly benefit directly from this vote on the program he led on for nearly 3 years. This appears to have caused grave damage to ICANN's credibility internationally drawing international Press and Governments criticism over conflict of interest. more

The Design of the Domain Name System, Part I

Over the past 30 years the Domain Name System has become an integral part of the operation of the Internet. Due to its ubiquity and good performance, many new applications over the years have used the DNS to publish information. But as the DNS and its applications have grown farther from its original use in publishing information about Internet hosts, questions have arisen about what applications are appropriate for publication in the DNS, and how one should design an application to work well with the DNS. more

Automated Theft of Intellectual Property

A few days ago I wrote about a piece of my intellectual property, an article I wrote and posted on DaileyMuse.com, being stolen, plagiarized, and posted on another web site under a different authors name. I hadn't been looking for my work elsewhere, I was simply browsing the access logs and visiting other websites that stood out. As a result of finding my work posted elsewhere without my permission, I contacted the owner of the website by email and provided 24 hours to remove the content before I pursued legal action. more

War of Words - the gTLD Weaponry

Why would the Association of National Advertisers (ANA), representing 400 member organizations and their 10,000 brands that spend $250 billion annually, be so wrong about ICANN's generic top-level domain (gTLD) program? They're complaining as if new gTLDs are being sold overnight in dark alleys with a no questions asked policy in exchange of a large suitcase filled with newly printed currency. This is definitely not the case, so what did they miss? more

Google Is NOT Moving Into the Mobile Phone Business

It might appear paradoxical for Google to buy a company for $12 billion and to then not move into that business, but I believe this is the strategy supporting that company's purchase of Motorola Mobility. As many have already pointed out, the value of Motorola resides in its patents. For more than a decade this company has been a fading star... more

The Need for Major Structural Changes

In keeping with the discussion that I have been involved in over the last decade, 'structural changes' should be today's key phrase - not just for the telecoms sector but for every sector in our economies. It has been clear for a long time that structural change is well overdue. It doesn't really matter which sector you pick, you will see that some of these reform debates go back at least a decade - and often longer -- in healthcare, education, environment, energy, finance and banking and media. more

Prediction Methods for Crime

There's a new sheriff in town and he's riding the horse of "predictive policing". Back in July the Santa Cruz Police Department began deploying police officers to places where crime is likely to occur in the future -- making use of new predictive modeling programs that are designed to provide daily forecasts of crime hotspots -- thereby allowing the Department to preempt more serious crimes before they occurred. In essence, this is another physical-world application of machine learning and clustering technologies -- applied to preempting a criminal problem. In the cyber-world we've been applying these techniques for a number of years with great success. more

A New Quality gTLD Can Compete with .COM

If you choose a new generic top-level domain (gTLD), will it be able to compete with .com? A recent academic paper indicates that the answer is yes if your new gTLD is of outstanding quality. "How Quality Drives the Rise and Fall of High-Tech Products" by professors Tellus, Yin, and Niraj in the Sloan Management Review provides evidence that new products can beat out established rivals... more

ICANN Chief Announces Departure Via Twitter

ICANN's CEO and President, Rod Beckstrom, has announced that he will be stepping down in July of next year. The announcement came via Twitter of all places, with a press release, presumably with more details, due sometime soon... With the launch of the new Top-Level Domain (TLD) program scheduled to officially launch early in 2012 maybe Beckstrom feels that his job "is done", or maybe there's another motive behind his departure. more

Will Googlerola Be Able to Fight Data Caps?

"Is Google Turning Into a Mobile Phone Company?" asks the headline in Andrew Ross Sorkin's New York Times story. Wrong question, IMHO. But is Google doing the deal at least partly to give it leverage over wireless providers? I think so. The biggest threat to the growth of Smart Phones and tablets and other Google businesses like YouTube is the imposition of data caps and metered pricing by wireless providers like at&t and Verizon Wireless. more
