China Continues to Add 30M Broadband Subscribers Per Year

China continues to add broadband subscribers at a rate of about 30M per year. MIIT puts the January growth at 2.5M to a total of 152.5M. Of those, about 1.5M were DSL. They don't release fiber counts, but Jeff Heynen of Infonetics is reporting tens of millions of lines of fiber gear are in the pipeline. China has been consistently at 2-3M net adds per month. Two key policy moves are likely to maintain or even increase the growth rate. more

Remarkable Internet History: Equifax Invented .COM in 1975

Once in a while, one comes across a new take on history that challenges everything you thought you knew. If you're the type who engages in bar bets with geeks, then this one is a certain gem. In 2001, Equifax submitted to the USPTO a sworn application to register a curious trademark, which eventually issued in 2004 with this data... Aside from the fact that Equifax has never actually held registration of the domain name efx.com, the truly outstanding fact here is that Equifax and/or its attorney has actually sworn to the United States Government that it was using "EFX.COM" as a mark for the provision of providing educational seminars via the internet since February 1975... Until now, I had imagined that Jon Postel added .com to the root in 1985. more

Webinar Tomorrow (May 22) - IPv6 and Telecom: IPv4 is Finally Running Out. Now What?

What is the impact of IPv6 on telecommunications, VoIP, unified communications, etc? Why should telecom operators care about IPv6? What VoIP systems already support IPv6? What efforts are underway within organizations like the IETF and the SIP Forum to ensure that telecommunications can work over IPv6? more

Internet Governance and Diplomacy

Developments in modern international relations have shown that traditional diplomacy is not capable of sufficiently addressing complex new issues, for example, the environment, health protection, and trade. Governance of the Information Society and the Internet is probably one of the most complex international issues facing diplomacy today. Issues surrounding the Information Society require a multi-disciplinary approach (the various concerns include technology, economy, impact on society, regulatory and legal issues, governance and more); a multi-stakeholder approach (various actors are involved, including states, international organizations, civil society, private sector, and others) and a multi-level approach (decision-making must take place on different levels: local, national, regional and global). Diplo has developed a research methodology which takes all of these approaches into account. Post includes illustration from Diplo Calendar 2004. more

Transport vs. Network

One of the basic tools in network design is the so-called "stacked" protocol model. This model was developed in the late 1970s as part of a broader effort to develop general standards and methods of networking. In 1983, the efforts of the CCITT and ISO were merged to form The Basic Reference Model for Open Systems Interconnection, usually referred to as the Open Systems Interconnection Reference Model or the "OSI model." more

How Big Is the Domain Business?

When you're standing close to ICANN, the domain business may seem pretty big, but when you stand farther away, not so much. Verisign's revenues are about $1 billion/year. The .COM and .NET top-level domains together have about 150M names. The next biggest gTLDS are .ORG with 25M and .INFO with 12M. The biggest new TLDs are TOP with 2.9M and .XYZ with 1.8M, with both bloated by firesale prices. The rest are smaller, mostly much smaller. more

ICANN Board: You Got It Right. Then You Got It Wrong. Now, Get It Right Again.

The ICANN Board has itself in a pretty pickle. The Governmental Advisory Committee (GAC) Consultancy with the Board in Brussels was an apparent non-starter. After hundreds of man-hours' worth of comments provided by the Intellectual Property Constituency (IPC), the Board continues to claim that it lacks sufficient information on trademark issues in order to respond to concerns. more

A Political Analysis of SPF and Sender-ID

In my spare time when I'm not dealing with the world of e-mail, I'm a politician so now and then I put on my cynical political hat. At the FTC Authentication Summit one of the more striking disagreements was about the merits and flaws of SPF and Microsoft's Sender-ID. Some people thought they are wonderful and the sooner we all use them the better. Others thought they are deeply flawed and pose a serious risk of long-term damage to the reliability of e-mail. Why this disagreement over what one might naively think would be a technical question? more

IPv6 Over Satellite: Pie in the Sky?

I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world... more

Consumer Trust? Not at ICANN Compliance

Every person and every entity must have a philosophy if they are to be successful. Consumer trust is one of the key issues at the heart of keeping the Internet open as well as prosperous. The ICANN Affirmation of Commitments was signed in 2009 and has been the guiding principle for ICANN's activities going forward. The title of section 9.3 is Promoting competition, consumer trust, and consumer choice. This section is in essence the embodiment of the commitment of ICANN. more

1 Terabit DDoS Attacks Become a Reality; Reflecting on Five Years of Reflections

Reflection amplification is a technique that allows cyber attackers to both magnify the amount of malicious traffic they can generate, and obfuscate the sources of that attack traffic. For the past five years, this combination has been irresistible to attackers, and for good reason. This simple capability, of turning small requests into larger, 'amplified' responses, changed the Distributed Denial of Service (DDoS) attack landscape dramatically. more

Verisign’s Perspective on Recent Root Server Attacks

On Nov. 30 and Dec. 1, 2015, some of the Internet's Domain Name System (DNS) root name servers received large amounts of anomalous traffic. Last week the root server operators published a report on the incident. In the interest of further transparency, I'd like to take this opportunity to share Verisign's perspective, including how we identify, handle and react, as necessary, to events such as this. more

The Highest Threat TLDs - Part 1

A domain name consists of two main elements: the second-level domain name to the left of the dot - often consisting of a brand name or relevant keywords - and the domain extension or top-level domain (TLD) to the right of the dot. Domain names form the key elements of the readable web addresses allowing users to access pages on the internet and also allowing the construction of email addresses. more

What are TLDs Good For?

Yesterday I said that the original motivations for adding new TLDs were to break VeriSign's monopoly on .COM, and to use domain names as directories. Competitive registrars broke the monopoly more effectively than any new domains, and the new domains that tried to be directories have failed. So what could a new TLD do? more

IPv6 Security Myth #10: Deploying IPv6 is Too Risky

After a quick break to catch our breath (and read all those IPv6 Security Resources), it's now time to look at our tenth and final IPv6 Security Myth. In many ways this myth is the most important myth to bust. Let's take a look at why... Myth: Deploying IPv6 Makes My Network Less Secure... I can hear you asking "But what about all those security challenges we identified in the other myths?" more
