Some Observations from NANOG 62

NANOG 62 was held at Baltimore from the 6th to the 9th October. These are my observations on some of the presentations that occurred at this meeting. .. One of the more memorable sides in this presentation was a reference to "map" drawn by Charles Minard in 1869 describing the statistics relating to the Napoleonic military campaign in Russia, and the subsequent retreat. 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

Four-Pronged Approach to Keep Your Domain Names and DNS Secure from Cyberattacks

Domain names, domain name systems (DNS), and digital certificates are fundamental components of the most important applications that enable your company to conduct business - including your website, email, voice-over IP, and more. However, these vital applications are being attacked with an increasingly high level of sophistication and severity. more

The Inextricable Issue of Internationalized Domain Names

ICANN has embarked on the IDN boat at the same time it wants to introduce DNSSEC and new gTLDs. This promises lots of fun. Or grey hair, depending how you look at it. First is the issue of country code IDNs. The ISO-3166 table, based on two letter codes, is a western convention. Some cultures do not use abbreviations or acronyms. Some do not use a character-based alphabet, but a syllabic one. Hence, the next logical step would be to represent the full country name in local script, rather than a transliteration of the ISO string... Imagine the case of India, where there are 1.652 languages, of which 24 are spoken by more than one million people... more

Your Cybersecurity is Only as Strong as Your Weakest Vendor

Managing the risk of third parties has become a compliance focus for many large organizations. Companies even work with third-party service providers and external vendors just to manage this risk. The recent SolarWinds attack escalates the critical need for chief compliance officers to collaborate with their business counterparts to identify and mitigate potentially unknown threats that lie within third-party supply chains. Yet how can companies manage this risk when it's not if but when you're attacked? more

Some Thoughts on the Recent DNS Operations, Analysis, and Research Centre Workshop, OARC-35

The DNS Operations, Analysis, and Research Centre (DNS-OARC) convened OARC-35 at the start of May. Here are some thoughts on a few presentations at that meeting that caught my attention... These days it seems that the term "the digital economy" is synonymous with "the surveillance economy." Many providers of services on the Internet spend a lot of time and effort assembling profiles of their customers. These days, it's not just data in terms of large-scale demographics but the assembling of large sets of individual profiles.  more

Thought Leaders Create New Trends & Solutions, Followers Just Follow - Which Are You?

Last week I asked on a post elsewhere, why we, at the MLi Group, chose to consider speakers, panelists, supporters and sponsors at our Global Summit Series (GSS) as "Thought Leaders" and "Trend Setters? Many wrote me directly offering their answers and then it dawned on me that my answer may (or may not) get appreciated by many at the ICANN community. So here is why we do. more

Some Internet Measurements

At APNIC Labs we've been working on developing a new approach to navigating through some of our data sets the describe aspects of IPv6 deployment, the use of DNSSEC and some measurements relating to the current state of BGP. The intent of this particular set of data collections is to allow the data to be placed into a relative context, displaying comparison of the individual measurements at a level of geographic regions, individual countries, and individual networks. more

Hacking Away at the Internet’s Security

The front page story of the September 13 2011 issue of the International Herald Tribune said it all: "Iranian activists feel the chill as hacker taps into e-mails." The news story relates how a hacker has "sneaked into the computer systems of a security firm on the outskirts of Amsterdam" and then "created credentials that could allow someone to spy on Internet connections that appeared to be secure." According to this news report this incident punched a hole in an online security mechanism that is trusted by hundreds of millions of Internet users all over the network. more

DNSSEC Takes Off in Wake of Root Zone Signing

The Domain Name System Security Extensions (DNSSEC) is a suite of IETF-developed specifications designed to validate information provided by the Domain Name System (DNS). ... When the root zone was signed in June 2010, this acted as a catalyst for TLD operators to deploy DNSSEC on their side. We have seen a gradual but significant increase in signed TLDs since then. The map in this post shows the level of DNSSEC deployment in Europe. more

Six Key Issues About Operating a TLD Registry

Brand owners unfamiliar with the domain name system (DNS) are hearing that their first step in registering a top level domain (TLD) is to select a back-end TLD registry provider. The fear instilled in them is that if they don't act quickly, all available service providers will have reached their capacity. Given ICANN's tight and inflexible application submission schedule, brands don't want to be left at the starting gate. more

13th Registration Operations Workshop: Join Us Online on June 4th, 2024

As a member of the ROW Planning Committee, I am writing this post on behalf of the Committee and welcome all community members to join us on June 4th. We are celebrating ROW's 10th anniversary! A decade of collaboration and inspiration! Thank you to the incredible community that has fueled this journey! more

DNS Resolvers and DNSSEC: Roll Over and Die?

Security is great when all the green lights are shining brightly and everything validates as intended, but what happens when you encounter failure? In this work we examine the behaviour of the DNS when security, in the form of DNSSEC is added, and we look at what happens when things do not happen as intended. What triggered this examination was a sudden increase in the traffic generated by secondary servers for the in-addr.arpa reverse zones in December 2009. more

Google Announces DNSSEC Support for Public DNS Service

Google today announced that its "Public DNS" service is now performing DNSSEC validation. Yunhong Gu, Team Lead for Google Public DNS, in post today wrote: "We launched Google Public DNS three years ago to help make the Internet faster and more secure.Today, we are taking a major step towards this security goal: we now fully support DNSSEC (Domain Name System Security Extensions) validation on our Google Public DNS resolvers." more

Secure Unowned Hierarchical Anycast Root Name Service - And an Apologia

In Internet Draft draft-lee-dnsop-scalingroot-00.txt, I described with my coauthors a method of distributing the task of providing DNS Root Name Service both globally and universally. In this article I will explain the sense of the proposal in a voice meant to be understood by a policy-making audience who may in many cases be less technically adept than the IETF DNSOP Working Group for whom the scalingroot-00 draft was crafted. I will also apologize for a controversial observation concerning the addition of new root name servers... more
