OARC held a 2-day meeting in February, with presentations on various DNS topics. Here are some observations I picked up from the presentations in that meeting... In a world where every DNS name is DNSSEC-signed, and every DNS client validates all received DNS responses, we wouldn't necessarily have the problem of DNS spoofing. Even if we concede that universal use of DNSSEC is a long time off ... more
Every few months, an important ceremony takes place. It's not splashed all over the news, and it's not attended by global dignitaries. It goes unnoticed by many, but its effects are felt across the globe. This ceremony helps make the internet more secure for billions of people. This unique ceremony began in 2010 when Verisign, ICANN and the U.S. Department of Commerce's National Telecommunications and Information Administration collaborated... more
The EU has been pushing for the development of DNS4EU, a public European DNS resolver with built-in filtering capabilities, as a way to strengthen the "digital sovereignty" of the EU and protect citizens, companies, and public institutions from phishing attacks and malware. In December 2021, a consortium of 13 public and private companies from ten European countries were granted the project to build a public DNS resolution service tailored for the EU. more
The IETF held its 115th meeting in London in November 2022. This was another in the set of hybrid meetings with specific support for online attendees in addition to the normal face-to-face meetings for the week. In no particular order, here are a few of my impressions from the IETF meeting. more
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
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
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
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
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
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
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
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
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 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
For over a decade, the Internet Corporation for Assigned Names and Numbers (ICANN) and its multi-stakeholder community have engaged in an extended dialogue on the topic of DNS abuse, and the need to define, measure and mitigate DNS-related security threats. With increasing global reliance on the internet and DNS for communication, connectivity and commerce, the members of this community have important parts to play in identifying, reporting and mitigating illegal or harmful behavior, within their respective roles and capabilities. more
