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

ICANN’s Accountability and Transparency – a Retrospective on the IANA Transition

As we passed five years since the Internet Assigned Numbers Authority transition took place, my co-authors and I paused to look back on this pivotal moment; to take stock of what we've learned and to re-examine some of the key events leading up to the transition and how careful planning ensured a successful transfer of IANA responsibilities from the United States Government to the Internet Corporation for Assigned Names and Numbers. 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

11th Registration Operations Workshop (ROW), June 21th, 2022, Online

The Registration Operations Workshop (ROW) was conceived as an informal industry conference that would provide a forum for discussion of the technical aspects of registration operations in the domain name system and IP addressing. The 11th ROW will be held online on Tuesday, June 21st, 2022 at 13h00 -- 16h00 UTC. The discussion topics will be... 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

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

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

Evolving From an Internet Registry to IoT Registry

As the name indicates, the Internet of Things (IoT) should be an extension of the Internet. However, in reality, most IoT applications are Siloed infrastructures. We will analyse the main challenges in the IoT and explain how an Internet registry could be evolved to provide a secure and privacy integrated Identity and access management service for IoT. more
