The DNS at the IGF

It's unclear what this means in the long run. Do bad actions and actors go undetected? Do we lose our visibility into network management? What is a "secure" network, and how do we secure it using traditional techniques of network perimeter traffic inspection when all the network traffic is opaque? If we can't see inside the DNS anymore, then how can we tell if (or when) the DNS has been captured by one or two digital behemoths? more

Some Random Notes from IETF 115

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

Achieving Multi-Stakeholder Progress on DNS Abuse

DNS Abuse and how to address it has been the topic of intense, often conflictual, and rarely conclusive discussions for many years, starting with the very definition of the term and the degree of responsibility bestowed upon DNS operators. In 2018, after several months of intersessional work, the Internet & Jurisdiction Global Conference brought together in Ottawa more than 200 key stakeholders to define a roadmap to address certain jurisdictional challenges on the Internet, including DNS abuse. more

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

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

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

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
