Measuring Root Server Performance

Root name servers are a core service of the Internet. As such they receive a huge amount of queries and need to answer reliably with acceptable delay. The RIPE NCC is responsible for operating one of the 13 DNS root name servers K-root which responds to 10,000 - 15,000 queries per second. Most root servers are operated as a network of distributed "instances" using anycast. more

Digging Through the Problem of IPv6 and Email - Part 1

Recently, a couple of anti-spam (or at least email security related) bloggers have written some articles about IPv6 and the challenges that the email industry faces regarding it. John Levine, who has written numerous RFCs and a couple of books about spam fighting, writes the following in his article "A Politically Incorrect Guide to IPv6, part III". more

What’s ARC?

DMARC is an anti-phishing technique that AOL and Yahoo repurposed last year to help them deal with the consequences of spam to (and apparently from) addresses in stolen address books. Since DMARC cannot tell mail sent through complex paths like mailing lists from phishes, this had the unfortunate side effect of screwing up nearly every discussion list on the planet. Last week the DMARC group published a proposal called ARC, for Authenticated Received Chain, that is intended to mitigate the damage. What is it, and how likely is it to work? more

The Longevity of the Three-Napkin Protocol

It is not often I go out to my driveway to pick up the Washington Post -- yes, I still enjoy reading a real physical paper, perhaps a sign of age -- and the headline is NOT about how the (insert DC sports team here) lost last night but is instead is about an IT technology. That technology is the Border Gateway Protocol (BGP), a major Internet protocol that has been around for more than a quarter century, before the Internet was commercialized and before most people even knew what the Internet was. more

“Internet Drivers License” - A Short History Lesson

The press, the blogosphere, CircleID - everybody has been discussing Craig Mundie's comment on the need for an "Internet Driver's License". Most of the reaction has been from privacy advocates fearing that this is simply another way to kill anonymity on the Internet. Oh well... that's the usual set of reactions. Now... the fun part is, a driver's license also shows that you have the competence to drive... more

How a DNS Proxy Service Can Reduce the Risk of VoIP Service Downtime

Consumers are embracing VoIP services now more than ever as they get used to calling over Internet application services such as Skype, Facetime, and Google Hangouts. Market Research Store predict that the global value of the VoIP services market is expected to reach above USD140 billion in 2021, representing a compound annual growth rate of above 9.1% between 2016 and 2021. more

Digital Economy + Sharing Economy = Networked Economy

A great deal of discussion is taking place about topics such as the digital economy, sharing economy and networked economy. Obviously these are concepts rather than being well-defined, but they are being used by the various players in the market to argue for or against certain developments. For example, in some of the broadband debates around the world, the digital economy is the key reason why national broadband infrastructure gets developed. more

Virtual Banishment and the First Amendment: Estavillo v. Sony Computer Entertainment of America

I saw this case in the excellent National Association of Attorneys General publication Cyber Crime e-newsletter. Many of us host or sponsor online communities of one form or another. On occasion, this means we must engage in moderation of the discourse in that community, and, as chance may arise, on occasion, we must give some chap the boot from the community for violating the AUP or the TOS. Inevitable, the booted chap screams "First Amendment Violation," to which we must respond, "The First Amendment restrains government actors -- we are not government actors." more

Learning from History: The Potsdam Call on Autonomous Weapon Systems

Eighty years ago, in August 1945, the world saw hope and horror. On August 1, 1945, just weeks after the adoption of the UN Charter, the leaders of the United States, the United Kingdom and the Soviet Union signed the Potsdam Agreement, which produced hope for a peaceful post-war world. Only some days later, the world saw the horror of nuclear bombs in Hiroshima and Nagasaki. A cold war followed. more

China’s Pursuit of Public International Cybersecurity Law Leadership

There are relatively few venues today for the development of public international cybersecurity law among Nation States. One was the United Nations Group of Governmental Experts (UNGGE) at which the U.S. several months ago announced its de facto withdrawal with some concern expressed. A much older, well-established venue is newly assuming considerable significance - the Expert Group on the International Telecommunication Regulations (EG-ITRs). more

A Programmer’s Perspective on the IANA Transition

Earlier this week, I posted from Singapore on the challenges we face in designing the transition of IANA functions from the US government to the global multistakeholder community. Now, let's consider how a programmer would design new mechanisms to accomplish this transition. For starters, a programmer would need something more than high-level principles. Coding requires use cases for routine interaction and especially for cases where users don't follow the expected routine and where the real world intervenes with inconvenient problems. more

Notice, Takedown, Borders, and Scale

I was on the front lines of the SOPA wars, because SOPA touched on two matters of strong personal and professional importance for me: protecting the Internet infrastructure, and protecting the economy from Internet related crime. I've continued to study this field and advise industry participants in the years since then. The 2017-02-20 paper by Annemarie Bridy entitled Notice and Takedown in the Domain Name System: ICANN's Ambivalent Drift into Online Content Regulation deserves an answer, which I shall attempt here. more

Transparency: The Internet’s Only Currency

I don't know about you, but I am angry. I am angry with the state of the world and our incapacity to do something about it. I am angrier because, in all this, I thought that the Internet would be the place where we would see collective action at its best. But, that's not going to happen. At least, anytime soon. Is it time to admit that the Internet has turned toxic? No. But, it is time to ask ourselves the question... more

Governing the Internet: The Model is the Message

In 1964, Canadian scholar Marshall McLuhan famously wrote, "The medium is the message." This phrase popped into my head last week as I listened to the opening speakers at the Internet Governance Forum in Nairobi. McLuhan meant that the form in which a message is delivered - the medium - embeds itself in the meaning of the message. The medium influences how the message is perceived and understood and is therefore inseparable from the message itself. What does this have to do with the Internet? more

Community Statement Presented at Wuzhen Summit

China is holding the First Internet Conference in the rivertown of Wuzhen, calling for global Internet interconnectivity and shared governance by all. Founders of China's top three Internet companies Alibaba, Tencent and Baidu as well as executives from global giants including Apple, Amazon, Google and Facebook all joined the gala. more
