DNS

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

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

The Danger of Weaponising the DNS in the Ukraine Russia Conflict and Good News

As we watch the Ukraine and Russia conflict over boundaries and territories, I chanced upon a YouTube video showing the region of Europe and how, for the last 1000 years, national boundaries and names of nations have changed where in 1142, you had nations like Muslim Spain, Kievan Rus. In 1143 the Kievan Rus included modern-day Ukraine and Crimea, and in 1163 bulk of Central and Southern Europe was the Holy Roman Empire... 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

How Not to Take Russia Off the Internet

Last week the Ukrainian government sent a letter to ICANN asking them to revoke the ".ru", ".рф" and ".su" top-level domains. It also said they were asking RIPE, which manages IP addresses in Europe, to revoke Russian IP addresses. Both ICANN and RIPE said no. Other people have explained why it would have been a policy disaster, but beyond that, neither would actually have worked. more

The Ever-Evolving Problem of DNS Abuse

For several years, many within ICANN circles have raised concerns about the escalating nature of domain name system (DNS) abuse. While some strides were made toward a safer DNS, new data - this time from a comprehensive study of DNS abuse by the European Union - demonstrates that abuse remains a frustratingly obstinate problem that requires urgent attention. We've seen some registries and registrars testing innovative industry-led initiatives in an effort to address the issues. 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

ICANN, Ukraine and Leveraging Internet Identifiers

Ukraine's representative to ICANN's Governmental Advisory Committee (GAC) has sent a letter to the Internet Corporation for Assigned Names and Numbers (ICANN) to remove Russian-administered top level domains (.RU, .SU and .рф) from the DNS root zone. In a separate letter, Ukraine's representative also asked RIPE NCC to withdraw the right to use all IPv4 and IPv6 addresses by all Russian members of the regional IP registry for the European region. more
