OARC-39: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

OARC held its fall meeting in Belgrade on October 22 and 23. Here are my impressions of some of the presentations from that meeting... UI, UX, and the Registry/Registrar Landscape - One of the major reforms introduced by ICANN in the world of DNS name management was the separation of registry and registrar functions. The intent was to introduce competition into the landscape by allowing multiple registries to enter names into a common registry. more

DNS Evolution: Innovation or Fragmentation?

There is no single name system that is necessarily bound to the Internet. Unlike IP addresses which are in every IP packet, names are an application construct, and, in theory, applications have considerable latitude in how they handle such names. There could be many name systems that could coexist within the Internet, in theory. In practice, there is strong peer pressure to use a single name system. more

Reexamining Internet Fragmentation

One of the discussion topics at the recent ICANN 75 meeting was an old favorite of mine, namely the topic of Internet Fragmentation. Here, I'd like to explore this topic in a little more detail and look behind the knee-jerk response of declaiming fragmentation as bad under any and all circumstances. Perhaps there are more subtleties in this topic than simple judgments of good or bad. more

Solving the “Fake Twitter Profile” Problem Using DNS

Recently, an article I wrote for Bitcoin Magazine talked about how we can use DNS underscore scoping to better abstract Lightning addresses and even create a de facto specification that could work on any resource (like a wallet or a smart contract) across all blockchains. more

Data, DNS Abuse and What to Do Next

To the annoyance of some, surely, the issue of abuse in the domain name system (DNS) has been high on the list of critical issues in internet governance circles. Personally, in my more than 20 years of internet governance experience, tackling DNS abuse is one of the more important issues I've participated in and seen debated. Despite this intense scrutiny, common-sense solutions (such as contract improvements) have been so far elusive, even as they fall squarely within its ICANN's remit. 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

More Mysterious DNS Root Query Traffic from a Large Cloud/DNS Operator

With so much traffic on the global internet day after day, it's not always easy to spot the occasional irregularity. After all, there are numerous layers of complexity that go into the serving of webpages, with multiple companies, agencies and organizations each playing a role. That's why when something does catch our attention, it's important that the various entities work together to explore the cause and, more importantly... more

NIS2 Directive Article 23 Will Lead to Inconsistencies and Conflicts Within the Domain Name Industry

On May 12th, European legislators head into their final trilogue negotiations around the NIS2 Directive. This week, the Internet Infrastructure Coalition (i2Coalition) shared guidance found below with negotiators, focused on the Directive's Article 23. i2Coalition has been detailing our concerns about Article 23 before even their public consultation in March 2021. more

CENTR Publishes Comment on the European Commission’s DNS Abuse Study

CENTR, which represents European national top-level domain name registries (ccTLDs) such as .si or .eu, has published its comments on the European Commission's DNS abuse study, calling out some of the "misleading analysis and unfortunate conclusions in the study." 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

Routing Without Rumor: Securing the Internet’s Routing System

The Domain Name System has provided the fundamental service of mapping internet names to addresses from almost the earliest days of the internet’s history. Billions of internet-connected devices use DNS continuously to look up Internet Protocol addresses of the named resources they want to connect to - for instance, a website such as blog.verisign.com. Once a device has the resource’s address, it can then communicate with the resource using the internet’s routing system. 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

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

Observations on Resolver Behavior During DNS Outages

When an outage affects a component of the internet infrastructure, there can often be downstream ripple effects affecting other components or services, either directly or indirectly. We would like to share our observations of this impact in the case of two recent such outages, measured at various levels of the DNS hierarchy, and discuss the resultant increase in query volume due to the behavior of recursive resolvers. more

ICANN DNS Resolver Symposium – the Session Had Several Interesting Presentations That I Would Like to Comment On

ICANN hosted a Resolver Operator Forum in mid-December, and the session had several interesting presentations that I would like to comment on here... The first presentation in this forum was from Paul Mockapetris. He pointed to the original academic published paper, Development of the Domain Name System, by Paul Mockapetris and Kevin Dunlap, published in the proceedings of ACM SIGCOMM’88. The paper noted that by 1983 it was obvious that the shared HOSTS.TXT file was not a scalable solution... more
