NXDOMAINS, SSAC’s SAC045, and New gTLDs (Part 4 of 5)

In 2010, ICANN's Security and Stability Advisory Committee (SSAC) published SAC045 [PDF], a report calling attention to particular problems that may arise should a new gTLD applicant use a string that has been seen with measureable (and meaningful) frequency in queries for resolution by the root system. The queries to which they referred involved invalid Top-Level Domain (TLD) queries (i.e., non-delegated strings) at the root level of DNS, queries which elicit responses commonly referred to as Name Error, or NXDomain, responses from root name servers.

The NameSentry Report: Benchmarking Abuse Levels in the Domain Name Industry

On July 10th Architelos released the first NameSentry Report, benchmarking abuse levels in the domain name industry. For some time now, a debate has raged about the potential impact of new gTLDs on Internet safety and security, namely abusive registrations such as phishing, spam, malware, and so on. However, without benchmarking the current state, how can we realistically evaluate if new gTLDs have made any measureable difference in the level of abuse?

The Internet: Missing the Light

Today's Internet is wonderful for solving hard problems such as connecting to Amazon to buy goods or for using Netflix. Amazon and Netflix, among others, demonstrate what is possible if you put in enough effort. Yet if we are to understand the Internet we need to look beyond those applications to the simplest application such as sending one bit of information from a light switch to a light fixture.

Avoiding an ICANN Monopoly on Policy

With all the focus in the TLD world on the imminent arrival of more than a thousand new TLDs and the still unfinished discussions within ICANN on what policy framework those TLDs will need to follow, it is often forgotten that there are hundreds of other TLD policy frameworks that are mature, stable and well tested. These of course are the ccTLD policy frameworks that have been actively developed over 20 years.

ICANN Chairman’s Durban Roundup

Respected ICANN Chairman of the Board Steve Crocker has wrapped up his organisation's 47th International Meeting, held in Durban last week, with a message to the community. This message, reproduced here in its entirety, provides both a useful and concise summary of the Durban meeting and insights into the Chairman's view of where ICANN stands at the moment, the successes it has notched up and the challenges it faces.

DNS, DNSSEC and Google’s Public DNS Service

For some time now we've been tracking the progress of the deployment of DNSSEC in the Internet. Its been a story of an evolution of the measurement technique... In the process we've learned perhaps more than we had wanted to about the behaviour of Flash engines, Apache web servers and FreeBSD system tuning, and also learned much more than we had anticipated about the finer details of Google's online ad presentation behaviour. But one thing we did not see in all of this was any large scale jumps in the level of client use of DNSSEC validation over this period at the start of the year.

First “Africa DNS Forum” To Be Streamed Live July 12 and 13 From Durban, South Africa

The first Africa DNS Forum will take place on Friday, July 12, and Saturday, July 13, 2013, in Durban, South Africa, in advance of next week's ICANN 47 meeting. Jointly organized by AfTLD, ICANN and the Internet Society, the Africa DNS Forum "aims to establish a platform for the DNS community across Africa and to advance the domain name industry and domain name registrations on the continent."

Passwords Are Not Enough: Without Two Factor Authentication Your Business Is At Risk

Passwords are no longer sufficient to maintain an adequate level of security for business critical infrastructure and services. Two-factor authentication should be considered the minimum acceptable level of access control. There have been two types of security stories in the technology news over the last few months that should be of particular concern to system administrators and those responsible for maintaining business network infrastructure.

The Missing Link in Dotless Domains

Well more than a year ago, ICANN's Security and Stability Advisory Committee published SSAC 053, its paper on single-label domain names - now referred to in the community as "dotless" domains - advising against their use. In a robust comment period, the community weighed in on the utility and safety of dotless domains, with some in favor and some opposed. To address the matter, ICANN has commissioned further study of the issue with an eye toward resolving the issue for new gTLD applicants.

No Surprise: Verisign’s Shift on New gTLDs

Five years after ICANN approved the new gTLD policy in Paris, two years after it approved the implementation plan in Singapore, and a year after the application window closed and some concrete steps were taken toward delegation of new gTLDs, a series of scary-sounding "what if" scenarios have mysteriously taken over discussions at ICANN. From colliding names and failing life support systems to mass confusion and technological outages, the profusion of horror stories has rivaled the hype for the Y2K conversion, with about as much basis in fact.
