The Design of the Domain Name System, Part VI - Overloaded Record Types

In the five previous exciting installments, we've been looking at aspects of the design of the DNS. Today we look at records types, and how you can tell what a DNS record means. All the records in the DNS are strongly typed. Each record includes an RRTYPE, a small number, which defines both the format of the record and what the record means. It is possible and common to have different record types with the same format, but different meanings. more

Biggest Botnet Takedown to Date

Yesterday law enforcement officials arrested 6 people and charged them with running a massive internet fraud ring. Over 4 million PCs were part of the botnet. According to the FBI, "the cyber ring used a class of malware called DNSChanger to infect approximately 4 million computers in more than 100 countries. There were about 500,000 infections in the U.S., including computers belonging to individuals, businesses, and government agencies such as NASA." more

Have you recently implemented DNSSEC or DANE and want to share your story? The deadline is Monday, August 17, so please send your proposal soon! We are open to proposals on a wide range of topics... more

Name Collisions II - A Call for Research

This post is a heads up to all uber-geeks about a terrific research initiative to try to figure out causes and mitigation of name-collision risk. There's a $50,000 prize for the first-place paper, a $25,000 prize for the second place paper and up to five $10,000 prizes for third-place papers. That kind of money could buy a lot of toys, my peepul. And the presentation of those papers will be in London -- my favorite town for curry this side of India. Interested? Read on. more

Three Years With ICANN

I joined the ICANN board during the December 2004 ICANN meeting in Cape Town. I served for a three year term and stepped down at this last meeting in Los Angeles and didn't run for another term... Before joining ICANN, I thought that ICANN was the only part of the Internet that wasn't really working. I knew that there must be a better way to do what ICANN does, but I couldn't be bothered to figure it out. I'd agree with people who said things like, "it should just be distributed" or "it should just be first come first serve" or "we should just get rid of it." People from ICANN would say, "it's more complicated than that" or "at this point that would be impossible." After being part of the process for three years, I find myself saying those same things... more

Authenticated Resolution and Adaptive Resolution: Security and Navigational Enhancements to the DNS

The Domain Name System (DNS) has become the fundamental building block for navigating from names to resources on the internet. DNS has been employed continuously ever since its introduction in 1983, by essentially every internet-connected application and device that wants to interact online. Emerging from an era where interconnection rather than information security was the primary motivation, DNS has gradually improved its security features. more

Luxembourg to Offer Investor-friendly Legal Environment for Domain Names

EuroDNS, the Luxembourg registrar, used its well attended New Year party last Wednesday to invite the Minister of Telecoms, Jean-louis Schiltz to talk about a law voted at the end of December 2007. According to the Finance and Budget Commission Report on Draft Law 5801, Revenues generated from use of, or license to use, a Domain Name are exempted from Luxembourg corporate taxes up to 80%. more

KerryEdwards.com Buyers Get Second Chance

The widely publicized auction of the domain name KerryEdwards.com ended Saturday night, but the search for a new owner continues. According to Matt Bentley, CEO of Sedo.com, the domain name brokerage managing the sale, a key bidder withdrew at a late stage in the auction, leaving the domain up for grabs among the dozen or so parties who had expressed a serious interest in purchasing the domain. more

I, the Domain Name Tasting Victim

I have recently been a "victim" of the domain name tasting "scam". A domain name (.COM) which is related to me personally (and which was owned by someone else previously) expired and as I knew from Whois (which is another debate on its own) that the expiry date was coming up, I kept a watch on when it would become available so I could register it. To cut a long story short, it took me nearly 6 weeks to get the domain. Each time the domain dropped off the 5 day grace period (it is not really something that would generate ad revenue), it would be picked up by a different registrant... more

The End of the Experiment

Amidst a firestorm of debate, the Internet Corporation for Assigned Names and Numbers (ICANN) has experimented with various forms of governance of the domain name system (DNS) involving input from the Internet community since its founding in 1998. ICANN's experimentation in running a representative and open corporate decision-making process has largely failed. This failure has manifested itself most explicitly by ICANN's retreat from its effort to enable the direct election of a subset of its Board members and, less explicitly, by the extent to which other efforts to engage the Internet user community in the decision-making process have proven ineffective. more

Happy Birthday .CAT and ICANN

Today, four years after the launch of the Catalan linguistic and cultural registry, Google reports that there are 90 million pages of Catalan content under the some 36 thousand .CAT domains. As imperfect as Google's tools are as a metric, the correct observation is that the use of .CAT by Catalans vastly exceeds the expectations of its initial proponents... more

When Businesses Go Dark: A DDoS Survey

In February 2012, Neustar surveyed IT professionals across North America to better understand their DDoS experiences. Most were network services managers, senior systems engineers, systems administrators and directors of IT operations. In all, 1,000 people from 26 different industries shared responses about attacks, defenses, ongoing concerns, risks and financial losses. 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

Internet Root Servers Hit with Unusual DNS Amplification Attack

On Nov. 30 and Dec. 1, several of the Internet Domain Name System's root name servers received high rate of suspicious queries, reaching as high as 5 million queries per second, according to a report released by the Root Server System Advisory Council. The incident has been categorized as a unique type of DNS amplification attack. more

DNS Security Flaw Secret Leaked Prior to Set Date: Patch DNS as Fast as Possible

In what seems to have started with a blog post by reverse engineer Halvar Flake, and subsequent blog postings from other experts in the know, the details of the recently announced DNS vulnerability was quite likely made public today. The DNS flaw was found earlier this year by security researcher Dan Kaminsky and earlier this month announced publicly along with various tools and patches provided by numerous vendors... more
