The Design of the Domain Name System, Part I

Over the past 30 years the Domain Name System has become an integral part of the operation of the Internet. Due to its ubiquity and good performance, many new applications over the years have used the DNS to publish information. But as the DNS and its applications have grown farther from its original use in publishing information about Internet hosts, questions have arisen about what applications are appropriate for publication in the DNS, and how one should design an application to work well with the DNS. more

TLD for Online Communities and Social Networking?

A company called PW Registry Corporation makes the following announcement regarding the .PW ccTLD originally designated for the country of Palau: "The PW Registry Corporation announced today plans for the activation of the PW top- level domain (TLD), the Internet's first and only domain extension devoted to "Communities of Shared Interests". Unlike other domain extensions, such as .com, .biz, and .info, PW is aimed at providing individuals and consumer/affinity organizations a highly-personalized, permanent and portable e-mail address and a managed platform for community and social networking." more

The Evolution of DNS: Adapting to the Changing Internet Landscape

The DNS is a crucial part of today's Internet. With the fracturing of the network's address space as a byproduct of IPv4 address run down and the protracted IPv6 transition the Internet's name space is now the defining attribute of the Internet that makes it one network. However, the DNS is not a rigid and unchanging technology. It has changed considerably over the lifetime of the Internet and here I'd like to look at what's changed and what's remained the same. more

Why Vint Cerf is Wrong

At the Internet Governance Forum in Baku, I made an intervention on behalf of NL IGF, reporting on the recommendations given by the participants of Workshop 87... I concluded that more regulatory and law enforcement bodies need to become part of the IGF discussions, as they are an integral part of governing the Internet from a safety and security perspective. Mr. Cerf responded with a one-liner: "I can't help observing, if we keep the regulatories confused, maybe they will leave us alone". more

Report on DNS Amplification Attacks

In this newly released paper Randal Vaughn and Gadi Evron discuss the threat of Distributed Denial of Service (DDoS) attacks using recursive DNS name servers open to the world. The study is based on case studies of several attacked ISPs reported to have on a volume of 2.8Gbps. One reported event indicated attacks reaching as high as 10Gbps and used as many as 140,000 exploited name servers. more

2004: The Year That Promised Email Authentication

As the year comes to a close, it is important to reflect on what has been one of the major actions in the anti-spam arena this year: the quest for email authentication. With email often called the "killer app" of the Internet, it is important to reflect on any major changes proposed, or implemented that can affect that basic tool that many of us have become to rely on in our daily lives. And, while many of the debates involved myriads of specialized mailing lists, standards organizations, conferences and even some government agencies, it is important for the free and open source software (FOSS) community as well as the Internet community at large, to analyze and learn lessons from the events surrounding email authentication in 2004. more

3rd Lawsuit Against VeriSign; Seeks Class Action Status

A third lawsuit has been filed late Friday in a federal district court in California against VeriSign, Inc. over its controversial DNS wildcard redirection service known as SiteFinder. It was filed by the longtime Internet litigator Ira Rothken. In addition, while two other lawsuits have been filed by Go Daddy Software, Inc. and Popular Enterprises, LLC. in Arizona and Florida, this is the first lawsuit to seek class-action status. Here is an excerpt from the "Introduction" section of this class-action lawsuit... more

Dr. Peering Commits Malpractice on Net Neutrality

At Tier1 Research, we hate to call out individuals for wrongdoing, but once in a while, it's absolutely necessary. At the moment, the Federal Communications Commission (FCC) is in the middle of the rulemaking process for network neutrality, a complex endeavor. While Tier1 is against interference from regulators as a concept, the proposed rulemaking document from the FCC, while vague, is not completely unreasonable... more

Success Drivers of New gTLD Applications

Being approved by the Internet Corporation for Assigned Names and Numbers (ICANN) as the owner of a new generic top-level domain (gTLD) extension requires considerable analysis before the application is submitted. You must understand the sources of risk, gauge your risk tolerance, and you must obtain an estimate of the value of your proposed TLD's future revenues (with the effects of potential competitors factored in, a step too many applicants ignore). more

The Darkening Web: Is there Light at the end of the Tunnel?

In his book "The Darkening Web: The War for Cyberspace" (Penguin Books, New York 2017), Alexander Klimburg, an Austrian-American academic, gives "Internet Dreamers" a "Wake Up Call". He tells us the background-story why people start to be "anxious about the future of the Internet", as the recent ISOC Global Internet Report "Paths to Our Digital Future" has recognized. Klimburg refers to Alphabets CEO Erich Schmidt, who once said that "the Internet is the first thing that humanity has built that humanity does not understand". more

Protecting the Internet: Certified Attachments and Reverse Firewalls?

In many respects the internet is going to hell in a hand basket. Spam, phishing, DNS poisoning, DDoS attacks, viruses, worms, and the like make the net a sick place. It is bad enough that bad folks are doing this. But it is worse that just about every user computer on the net offers a nice fertile place for such ill behavior to be secretly planted and operated as a zombie under the control of a distant and unknown zombie farmer. ...Some of us are coming to the converse point of view that the net is being endangered by the masses of ill-protected machines operated by users. more

Patching is Hard

There are many news reports of a ransomware worm. Much of the National Health Service in the UK has been hit; so has FedEx. The patch for the flaw exploited by this malware has been out for a while, but many companies haven't installed it. Naturally, this has prompted a lot of victim-blaming: they should have patched their systems. Yes, they should have, but many didn't. Why not? Because patching is very hard and very risk, and the more complex your systems are, the harder and riskier it is. more

The Coding of Online Brand Protection

Moore's law postulates that the number of transistors in an integrated circuit will double every two years. That law has given us smartphones and other devices with astonishingly diverse capabilities at ever lower costs. However, while it does not encompass online brand infringement, many trademark managers feel that their task is likewise expanding at exponential speed and imposing escalating costs. Potential cybersquatting based in the more than one thousand new generic top level domains is only one new source of anxiety. While the jury is still out on the level of harmful cybersquatting and the efficacy of the new Rights Protection Mechanisms (RPMs) for new gTLDs, that ICANN program is hardly the only challenge. more

Network Neutrality is the Wrong Fight!

We shouldn't settle for network neutrality. It's a poor substitute for what we had and much less than what we need. Let me explain. There are two topics to discuss. The first is "common carriage," a centuries old legal concept that applied to the US telecom industry throughout most of the 20th century. The second involves communications protocols. Both topics are complex, so I will cover only what's needed to understand why we shouldn't accept network neutrality and why, at a minimum, we should fight for enforcement of existing common carriage rules. more

Mitigating DNS Abuse and Safeguarding the Internet

The internet is a beacon of global connectivity and information, but it has also become a battleground where malicious actors exploit vulnerabilities for various immoral purposes. Domain Name System (DNS) abuse stands has proven a constant in the internet threat landscape, posing risk to the overall digital trust. more
