The Internet Must Remain Open - Even for Those We Disagree With

Over the past couple of weeks, following the events in Charlottesville, Virginia, there has been significant discussion in social and traditional media about various technology companies removing websites from their servers, or otherwise making them unavailable. As the operators of Canada's Internet domain, we at CIRA are getting numerous inquiries about our stance and policies on this issue. I'd like to use this opportunity to make a couple of clarifications about how CIRA works and what CIRA actually does. more

Evolution of the Dot Brand Domains in 5 Years

ICANN's last new gTLD application closed in 2012 with more than 600 brands applying for their dot brand. Dot brand domains associate a keyword or keyphrase and a brand name in a complete domain name... To understand better how the evolution of the dotBrand has been throughout these years, number of websites launched, redirects, registries etc, Dot Brand Observatory prepared a few visual graphics. more

Probability of ROI and Tighter Network Security by Blocking Malicious Subdomains

Failing to block a stealthy malicious host from making connections to your network could cost your company millions of dollars, a damaged reputation, and severe losses in sensitive private data. Threat intel teams have faced on-going problems: Expensive feeds that are slow to catch new threats; Chasing false positives in alerts wastes time and money; and Vendors selling a new appliance for every ill. Would 100% of your users Spot the Bot? more

The Internet is Dead - Long Live the Internet

Back in the early 2000s, several notable Internet researchers were predicting the death of the Internet. Based on the narrative, the Internet infrastructure had not been designed for the scale that was being projected at the time, supposedly leading to fatal security and scalability issues. Yet somehow the Internet industry has always found a way to dodge the bullet at the very last minute. more

Supporting New DNS RR Types with dnsextlang, Part II

Previous article introduced my DNS extension language, intended to make it easier to add new DNS record types to DNS software. It described a new perl module Net::DNS::Extlang that uses the extension language to automatically create perl code to handle new RRTYPEs. Today we look at my second project, intended to let people create DNS records and zone files with new RRTYPEs. more

Is a New Set of Governance Mechanism Necessary for the New gTLDs?

In order to be able to reply to the question of whether a new set of governance mechanisms are necessary to regulate the new Global Top Level Domains (gTLDs), one should first consider how efficiently the current Uniform Domain-Name Dispute-Resolution Policy (UDRP) from the Internet Corporation for Assigned Names and Numbers (ICANN) has performed and then move to the evaluation of the Implementations Recommendations Team (ITR) recommendations. more

Supporting New DNS RR Types with dnsextlang, Part I

The Domain Name System has always been intended to be extensible. The original spec in the 1980s had about a dozen resource record types (RRTYPEs), and since then people have invented many more so now there are about 65 different RRTYPEs. But if you look at most DNS zones, you'll only see a handful of types, NS, A, AAAA, MX, TXT, and maybe SRV. Why? A lot of the other types are arcane or obsolete, but there are plenty that are useful. more

Nation Scale Internet Filtering—Do’s and Don’ts

If a national government wants to prevent certain kinds of Internet communication inside its borders, the costs can be extreme and success will never be more than partial. VPN and tunnel technologies will keep improving as long as there is demand, and filtering or blocking out every such technology will be a never-ending game of one-upmanship. Everyone knows and will always know that determined Internet users will find a way to get to what they want, but sometimes the symbolic message is more important than the operational results. more

Phishing: the Worst of Times in the DNS

The Anti-Phishing Working Group has released its latest Global Phishing Survey, written by myself and Rod Rasmussen. This report comprehensively examines a large data set of more than 250,000 confirmed phishing attacks detected in 2015 and 2016. By analyzing this cybercrime activity, we have learned more about what phishers have been doing, and how they have done it. Unfortunately, there's more phishing than ever, and phishers are registering more domain names than ever. more
