Domain Names

The Netizen's Guide To Reboot The Root (Part I)

In the world of ICANN and Internet policy, complexity is manufactured to create an illusion that issues are impenetrably technical such that normal and everyday principles can't apply. This causes a pervasive and entrenched phenomenon of eyes that glaze over at the mere mention of the word "ICANN" -- including those of government regulators and other officials that might otherwise take more of an active interest. more

Securing the DNS in a Post-Quantum World: New DNSSEC Algorithms on the Horizon

One of the "key" questions cryptographers have been asking for the past decade or more is what to do about the potential future development of a large-scale quantum computer. If theory holds, a quantum computer could break established public-key algorithms including RSA and elliptic curve cryptography (ECC), building on Peter Shor's groundbreaking result from 1994. more

WHOIS Record Redaction and GDPR: What's the Evolution Post-2018?

We all use the Internet daily. Practically every element of our reality has its equal in the virtual realm. Friends turn into social media contacts, retail establishments to e-commerce shops, and so on. We can't deny that the way the Internet was designed, to what it has become, differs much. One example that we'll tackle in this post is the seeming loss of connection between domains and their distinguishable owners. more

Verisign Outreach Program Remediates Billions of Name Collision Queries

A name collision occurs when a user attempts to resolve a domain in one namespace, but it unexpectedly resolves in a different namespace. Name collision issues in the public global Domain Name System (DNS) cause billions of unnecessary and potentially unsafe DNS queries every day. A targeted outreach program that Verisign started in March 2020 has remediated one billion queries per day to the A and J root name servers, via 46 collision strings. more

Newer Cryptographic Advances for the Domain Name System: NSEC5 and Tokenized Queries

In my last post, I looked at what happens when a DNS query renders a "negative" response -- i.e., when a domain name doesn't exist. I then examined two cryptographic approaches to handling negative responses: NSEC and NSEC3. In this post, I will examine a third approach, NSEC5, and a related concept that protects client information, tokenized queries. The concepts I discuss below are topics we've studied in our long-term research program as we evaluate new technologies. more

Brand Protection Beyond the "Whack-a-Mole" Approach

I recently shared at a conference how a seasoned brand and fraud expert from one of the world's largest global financial institutions lamented a major attack where multiple fraudulent websites would pop up every single day. All attacks were launched from the same registrar and web hosting company, and no matter how much they reached out to these providers, they received the same reply: "we will pass on your request to the registrant or site owner," and then nothing happened. more

More Warning Shots for ICANN, or the End of the Road?

Last fall, I wrote about ICANN's failed effort to achieve its goal of preserving the Whois domain name registration directory to the fullest extent possible. I predicted that if the policy effort failed, governments would take up the legislative pen in order to fulfill the long-ignored needs of those combating domain name system harms. That forecast has now come true through significant regulatory actions in the United States and the European Union in the form of a proposed directive from the European Commission (EC) and instruction from the US Congress to the National Telecommunications and Information Administration (NTIA). more

Cryptographic Tools for Non-Existence in the Domain Name System: NSEC and NSEC3

In my previous post, I described the first broad scale deployment of cryptography in the DNS, known as the Domain Name System Security Extensions (DNSSEC). I described how a name server can enable a requester to validate the correctness of a "positive" response to a query -- when a queried domain name exists -- by adding a digital signature to the DNS response returned. more

Digital in 2021 – Five Predictions for Brand Protection

While smartphones were an integral part of our lives before 2020, now, as a result of the changes associated with COVID, our mobile devices are virtually "super-glued" to our hands. The worldwide pandemic has heavily influenced our lives. Based on our past experiences with digital brand protection and the trends we're currently seeing, we've made five predictions regarding the future of internet usage in 2021. more

The Domain Name System: A Cryptographer's Perspective

As one of the earliest protocols in the internet, the DNS emerged in an era in which today's global network was still an experiment. Security was not a primary consideration then, and the design of the DNS, like other parts of the internet of the day, did not have cryptography built in. Today, cryptography is part of almost every protocol, including the DNS. And from a cryptographer's perspective, as I described in my talk at last year's International Cryptographic Module Conference (ICMC20), there's so much more to the story than just encryption. more

Exploring the Meanings of "Right" and "Legitimate Interest" (UDRP Proceedings)

For complainant, the second leg in determining cybersquatting under the Uniform Domain Name Dispute Resolution Policy (UDRP) is evidence respondent lacks both rights and legitimate interests in the challenged domain name (Paragraph 4(a)(ii)). I underscore "both" because proving one but not the other is not good enough. This seems obvious, so why suggest there is something to explore about "rights" and "legitimate interests" if their meanings hardly need explication? more

.com Is A Clear and Present Danger to Online Safety

"The Internet is the real world now." This assessment was offered by Protocol, a technology industry news site, following the very real violence on Capitol Hill during the counting of the electoral college votes that officially determines the next president of the United States. The media outlet went on to say that, "[t]he only difference is, you can do more things and reach more people online -- with truth and with lies -- than you can in the real world." more

2020 Domain Name Year in Review

2020 - a year like no other. The impact of COVID on the domain name industry was felt far and wide as ICANN meetings were held virtually, travel was cancelled, TLD launches were delayed, the topic of domain name abuse was front and center, and we all tried to navigate a "new" normal. Unlike many sectors, the domain name industry was fortunate and, in many ways, survived 2020 unscathed. Much of our industry was able to continue working from home after an initial period of adjustment. more

What Are the Connected Assets of Confirmed Fake FBI Domains?

Two months ago, the Federal Bureau of Investigation (FBI) alerted the public to a list of domains that could easily be mistaken to be part of its network. The list of artifacts contained a total of 92 domain names, 78 of which led to potentially malicious websites, while the remaining 14 have yet to be activated or are no longer active as of 23 November 2020. more

NTIA Objects to Planned o.com Auction

According to media sources, the National Telecommunications and Information Administration (NTIA) wrote to Verisign last Friday, objecting to the company's plan to auction o.com to the highest bidder. The planned release for o.com - described by the Second Amendment to the .com Registry Agreement and intended as a pilot for the remaining reserved single-character .com names - involved an opaque consideration process that ignored community input and set aside hard-won trademark protections developed by stakeholders in order to maximize dollars earmarked for an unidentified cadre of non-profit organizations. more
