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

DNS Abuse Institute Launches Centralized DNS Abuse Reporting Service

The DNS Abuse Institute (DNSAI), the entity created by Public Interest Registry (PIR), today announced the launch of NetBeacon, a centralized DNS Abuse reporting service. NetBeacon was developed in collaboration with CleanDNS, an anti-abuse solution developer, which has donated the development and technology behind NetBeacon. more

Trusted Notifier Arrangements Require Trust: Why Unpacking Misunderstandings Around Trusted Notifiers Is Important for Dealing With DNS-related Abuse

Domain Name System (DNS) Operators (Registries and Registrars) receive notices asking them to take action on a wide range of alleged technical and content-related abuses. However, there is a fundamental question of when it is appropriate to act at the DNS level and the evaluation of whether the alleged abuse meets a sufficient threshold for action at the DNS level. Additionally, given the volume of abuses occurring on the internet, existing resources, mechanisms, and protocols available in-house to Operators are in many cases insufficient to address abuses in a timely fashion. more

Recursive DNS and You

In the world of DNS, there are two types of DNS servers, 'recursion disabled' and 'recursion enabled'. Recursion disabled servers, when asked to resolve a name, will only answer for names that they are authoritative for. It will absolutely refuse to look up a name it does not have authority over and is ideal for when you don't want it to serve just any query. It isn't, however, very useful for domains you don't know about or have authority over... more

Ukrainian Representatives to ICANN Ask for Russia’s Domain to Be Revoked, Local DNS Root Servers Shut Down

A letter sent to ICANN and IANA by a Ukrainian representative to ICANN’s Government Advisory Council (GAC) asks for urgent and strict sanctions against the Russian Federation in “the field of DNS regulation.” The letter urges ICANN to permanently or temporarily revoke Russia’s top-level domains “.ru”, “.рф” and “.su” and to shut down DNS root servers located in Saint Petersburg and Moscow. more

Decentralizing Cybersecurity Via DNS

Decentralization is a big trend in IT, and everyone has their own definition of what "decentralization" really means. With more organizations fully embracing a work-from-anywhere culture, decentralization has moved past being a fad and turned into a necessity. Decentralized cybersecurity is nothing new. Many of us have been doing it since before the pandemic. more

ICANN67 Round-Up

This past meeting of the Internet Corporation for Assigned Names and Numbers (ICANN), ICANN67, was intended to be held in person in Cancun, Mexico, but was actually the first meeting to be held entirely online and virtually. It was a well-managed affair with fewer sessions than the in-person meetings and less opportunity for the community to convene and meet as individuals. The last-minute change from an in-person to a virtual meeting impacted ICANN's ability to provide translation services for the full set of UN-supported languages, Arabic, Chinese, English, French, Russian, and Spanish. more

Multi-Stakeholder Internet Governance Is Captured and Presumed Dead

Technical management of the Internet was delegated to ICANN by the U.S. government because it was believed that the private sector would be more agile and responsive to the needs of globally distributed stakeholders. However, this optimism and the faith it has produced has proven to be misplaced since ICANN's multi-stakeholder governance continues falling far short of the basic expectations set when it was created. more

Mobilizing the Internet Community for Coronavirus Pandemic Communications

The Coronavirus pandemic has profound impact on every aspect of every person's life. We all have turned to the Internet to stay informed on this one subject. Unfortunately, the Internet community is not equipped to organize the Internet around one subject. Governments and businesses are reorganizing their websites daily to make new paths to new coronavirus information on many topics suitable for their many audiences. more

The World of the Subdomain

A web domain name is the foundational piece of internet property allowing its owner (registrant) to construct and host an associated website. On a domain, the owner is also able to construct whatever subdomains they wish -- a process that is technically achieved via the configuration of records on the authoritative domain name system (DNS) server. more

Call for Participation – ICANN DNSSEC and Security Workshop for ICANN74 Policy Forum

Do you have information about DNS security or routing security that you would like to share with the global community? Have you developed a new tool or system in this area? Do you have results from a research project that you want to share with a technical community? If so, please consider submitting a proposal to the DNSSEC and Security workshop to be held at ICANN 74 in June 2022. more

ICANN Is Violating Its Legal Agreements with the U.S. Government – Who’s Next?

In April, I published an article, The Multistakeholder Moment of Truth: Will Stakeholders Hold ICANN Accountable?, alerting stakeholders that ICANN is violating its legal agreements with the U.S. Government -- namely the InterNIC licensing agreement and merged Memorandum of Understanding. At that time, I warned that it is essential for stakeholders not to remain silent in the face of this transgression, "hoping that such behavior left unchecked will end of its own accord." more
