DNS Resolvers and DNSSEC: Roll Over and Die?

Security is great when all the green lights are shining brightly and everything validates as intended, but what happens when you encounter failure? In this work we examine the behaviour of the DNS when security, in the form of DNSSEC is added, and we look at what happens when things do not happen as intended. What triggered this examination was a sudden increase in the traffic generated by secondary servers for the in-addr.arpa reverse zones in December 2009. more

Where Did “Data Shadow” Come From?

Anyone who works in privacy is familiar with the term "data shadow": the digital record created by our transactions, our travels, our online activities. But where did the phrase come from? Who used it first? A number of authors have attributed it to Alan Westin, whose seminal book Privacy and Freedom (largely a report on the work of the Committee on Science and Law of the Association of the Bar of the City of New York) set the stage for most modern discussions of privacy.  more

Google Launch of DNS Service and OpenDNS Reply

Earlier today Google announced the launch of their new DNS service. They're pushing it as part of their "better experience" and "speed" drive that Matt Cutts and Co have been harping on about for the last while. OpenDNS, however, has been offering a similar service for quite some time... So it was quite interesting to read OpenDNS' response to the Google service. more

Proving Common Law Rights Predating Domain Name Registration

The trademark rights required for standing under paragraph 4(a)(i) of the Uniform Dispute Resolution Policy (UDRP) refer to both registered and unregistered rights. Complainants with registered trademarks satisfy the requirement by submitting their certificates of registration. However, and not surprisingly, complainants with unregistered trademarks have to demonstrate that the alleged marks qualify as such, which requires that complainants prove both secondary meaning of the marks and their distinctiveness prior to the registration of the domain name. more

How the Registrar Cash Flow Model Could Collapse with New ICANN gTLDs

New top-level domain applicants are getting plenty of advice nowadays about how to launch their new Registry. In addition to thinking about their branding and distribution, they should also be thinking about their business practices with Registrars. What many of them do not realize is that their cash flow practices, with respect to Registrars, may be a factor of whether ICANN Registrars even support their Registry. more

Email Recommendation Engine for ESPs – Text Length Optimization (Part II)

Popular email editors today have no way to optimize for text length. An email marketer may attempt to build her content but has no idea whether that content is optimized related to word count for a specific industry/client. As it relates only to text length, does the email have too many or too few words. Currently, there is no built-in predictive model to inform her. Well, until now. Last month we described an evolutionary real-time data-driven process for email campaign builders to have at their disposal. more

Gruber Gives Up On His IDN

Tech pundit John Gruber threw in the towel on his domain ?df.ws. He writes: "What I didn't foresee was the tremendous amount of software out there that does not properly parse non-ASCII characters in URLs, particularly IDN domain names." more

Why Wireless Broadband Is No Alternative to FttH

The mainly politically-driven debate - FttH versus wireless broadband - is spreading uninformed messages and half-truths in the market. And confusing messages from mobile operators are also blurring the picture. All well-informed people confirm that this is a nonsensical debate -- both infrastructures will coexist with, and supplement, each other. more

The Changing Role of IP Addresses in the Architectural Evolution of the Internet

I work at APNIC, the Regional Internet Registry that serves the Asia Pacific Region. APNIC provides common infrastructure services for the region that support the unique assignment of IP address blocks to Internet network operators within our region through the operation of an address registry. In short, IP addresses are what we do. So, when there are discussions in technology circles about evolving the Internet's address model in varying ways,... more

How Fast is Starlink Broadband?

We got a recent analysis of Starlink broadband speeds from Ookla, which gathers huge numbers of speed tests from across the country. The U.S. average download speeds on Starlink have improved over the last year, from an average of 65.72 Mbps in 1Q 2021 to 90.55 Mbps in 1Q 2022. But during that same timeframe, upload speeds got worse, dropping from an average of 16.29 Mbps in 1Q 2021 to 10.70 Mbps in 1Q 2022. more

An Open Letter to Big Tech CFOs: Save the Internet Before You’re Forced

Dear Chief Financial Officers of tech giants, the internet is in crisis, and you can lead your organization to help solve the problem. You'll be well compensated, and you'll enjoy massive public relations benefits. I fear that if you don't, global governments will force your hand. There is a shortage of available IPv4 addresses but we are years away (possibly a decade or more) from IPv6 viability and adoption in North America. more

Information Protection for the Domain Name System: Encryption and Minimization

In previous posts in this series, I've discussed a number of applications of cryptography to the DNS, many of them related to the Domain Name System Security Extensions (DNSSEC). In this final blog post, I'll turn attention to another application that may appear at first to be the most natural, though as it turns out, may not always be the most necessary: DNS encryption. (I've also written about DNS encryption as well as minimization in a separate post on DNS information protection.) more

Deep Packet Inspection: When the Man-In-The-Middle Wants Money

Say you're walking down the sidewalk having a talk with your best friend about all kinds of things. What if you found out later that the sidewalk you were using wasn't really a sidewalk -- but instead a kind of false-front giant copying machine, unobstrusively vacuuming up what you were saying and adding to its database of information about you? Or, say you send a letter to a client of yours (to the extent you still do this), and it turns out later that your letter was intercepted, steamed open, and the contents were read... more

The Rise of a Secondary Market for Domain Names (Part 4/4): Facilitating the Secondary Market

The defining of rights in the UDRP process is precisely what WIPO and ICANN contemplated, but it is unlikely they foresaw the destination of the jurisprudence. Since its inception, UDRP Panels have adjudicated over 75,000 disputes, some involving multiple domain names. (These numbers, incidentally, are a tiny fraction of the number of registered domain names in legacy and new top-level domains, which exceeded 320 million in the first quarter 2017). more

NTIA’s New Broadband Map

The National Telecommunications and Information Administration surprised the broadband industry by issuing a new broadband map for the whole U.S. The map differs in dramatic ways from the FCC's broadband map, which is derived from broadband speeds that are reported by the ISPs in the country. It's commonly understood that the FCC broadband map overstates broadband coverage significantly. The NTIA map draws upon varied sources in an attempt to create a more accurate picture of the availability of broadband. more
