Evolution of the Dot Brand Domains in 5 Years

ICANN's last new gTLD application closed in 2012 with more than 600 brands applying for their dot brand. Dot brand domains associate a keyword or keyphrase and a brand name in a complete domain name... To understand better how the evolution of the dotBrand has been throughout these years, number of websites launched, redirects, registries etc, Dot Brand Observatory prepared a few visual graphics. more

DNSAI Compass: Six Months of Measuring Phishing and Malware

The DNS Abuse Institute recently published our sixth monthly report for our project to measure DNS Abuse: DNSAI Compass ('Compass'). Compass is an initiative of the DNS Abuse Institute to measure the use of the DNS for phishing and malware. The intention is to establish a credible source of metrics for addressing DNS Abuse. We hope this will enable focused conversations, and identify opportunities for improvement. more

Use of DNS Firewalls Could Have Prevented More Than $10B in Data Breach Losses Over the Past 5 Years

New research from the Global Cyber Alliance (GCA) released on Wednesday reports that the use of freely available DNS firewalls could prevent 33% of cybersecurity data breaches from occurring. more

Observations on Resolver Behavior During DNS Outages

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

DNSSEC Happy Talk Enters a New Era

So we finally have a signed root zone. Now when is someone going to answer the question I first asked over five years ago and have still not had an answer to: How do the domain name owner's keys get into the TLD? Before we have a system people can use there have to be technical standards, validation criteria and a business model. Where are they? more

How to Prepare for the DNSSEC Root KSK Rollover on October 11, 2018

Are you ready? Are your systems prepared so that DNS will keep functioning for your networks? One week from today, on Thursday, October 11, 2018, at 16:00 UTC ICANN will change the cryptographic key that is at the center of the DNS security system - what we call DNSSEC. The current key has been in place since July 15, 2010. This is a long-planned replacement. more

DNS Wars

The North American Network Operators' Group (NANOG) is now quite an institution for the Internet, particularly in the North American Internet community. It was an offshoot of the Regional Techs meetings, which were part of the National Science Foundation Network (NSFNET) framework of the late 80s and early 90s. NANOG has thrived since then and is certainly one of the major network operational forums in today's Internet – if not the preeminent forum for network operators for the entire Internet. more

Domain Pulse 2008: Day 2 Focuses on DNS Security

Day two of Domain Pulse 2008 last Friday (see review of day one) focused on online security issues giving the techies amongst us details of security issues, and the more policy-orientated amongst us something to chew on in a few other presentations. Kieren McCarthy, these days of ICANN, also gave some insights into the drawn out sex.com drama with more twists and turns than the average soap opera has in a year! And Randy Bush outlined the problems with IPv6. Among other presentations... more

Will a Global TAR Make DNSSEC Stick?

Two US Government contractors and the National Institute of Science and Technology have released a white paper, "Statement of Needed Internet Capability," detailing possible alternatives and considerations for a Trust Anchor Repository (TAR) to support DNSSEC deployment. The document was released through the DNSSEC-Deployment Group this week with a request that it be circulated as widely as possible to gather feedback. A Trust Anchor Repository (TAR) refers to the concept of a DNS resource record store that contains secure entry point keys... more

Call for Nominations: M3AAWG J. D. Falk Award Seeks Stewards of a Better Online World

Anyone seeking to honor a groundbreaking contribution toward a better online world should submit a nomination for the 2014 M3AAWG J. D. Falk Award. Presented to people whose work on specific projects made the Internet a safer, more collaborative, more inclusive place, the J. D. Falk Award has recognized leaders and pioneers who saw elements of the online experience that needed improvement and took action to fix them.  more

DNSSEC is But One Link in the Security Chain

As the implementation of DNSSEC continues to gather momentum and with a number of ccTLDs, and the '.org' gTLD having deployed it into their production systems, I think it is worth pausing to take a look at the entire DNSSEC situation. Whilst it is absolutely clear that DNSSEC is a significant step forward in terms of securing the DNS, it is but one link in the security chain and is therefore not, in itself, a comprehensive solution to fully securing the DNS system. more

The Spamhaus Distributed Denial of Service - How Big a Deal Was It?

If you haven't been reading the news of late, venerable anti-spam service Spamhaus has been the target of a sustained, record-setting Distributed Denial-of-Service (DDoS) attack over the past couple of weeks... Of course, bad guys are always mad at Spamhaus, and so they had a pretty robust set-up to begin with, but whoever was behind this attack was able to muster some huge resources, heretofore never seen in intensity, and it had some impact, on the Spamhaus website, and to a limited degree, on the behind-the-scenes services that Spamhaus uses to distribute their data to their customers. more

ICANN 35: What’s Going Down, Down Under (Want the Low Down?)

As I've been getting ready to catch my plane for ICANN 35 (Sydney), I can't help but thinking that there are a lot of things going down these days that will dramatically affect makeup of the Internet for years to come. Next year at this time, the root could be a very, very different place. A few of the items that will be getting deconstructed, discussed, debated Down Under are outlined below... more

ICANN 36 Preview: What’s ‘On Sale’ in Seoul

Last time the ICANN faithful gathered in Sydney, there was a fair bit of unrest and some big unknowns. The Implementation Recommendation Taskforce (IRT) report on how Intellectual Property (IP) could be protected in the era of new Top-Level Domains (TLDs) stirred the pot as did, to a lesser extent, the issue of Registry-Registrar separation in new TLDs. Additionally, everyone had big questions on their minds - when the root would be signed (and DNSSEC fully implemented)... Four months later and five thousand miles almost due north, the netizens gathering at ICANN 36 in Seoul know the answers to some of those very important questions. more

Microsoft Announces Plans to Adopt DoH in Windows

Microsoft announced today its plans to adopt DNS over HTTPS (DoH) protocol in Windows and will also keep other options such as DNS over TLS (DoT) on the table for consideration. more
