Top-Level Domains

A top-level domain (TLD), is the last part of an Internet domain name; that is, the letters which follow the final dot of any domain name. For example, in the domain name www.example.com, the top-level domain is com (or COM, as domain names are not case-sensitive). Management of top-level domains is handled by the ICANN. Top-level domains are classified into three types: country code top-level domains (ccTLD): Used by a country or a dependent territory. It is two letters long, for example .us for the United States. With some historical exceptions, the code for any territory is the same as its two-letter ISO 3166 code. generic top-level domains (gTLD): Used (at least in theory) by a particular class of organizations (for example, .com for commercial organizations). It is three or more letters long. Most gTLDs are available for use worldwide, but for historical reasons .mil (military) and .gov (governmental) are restricted to use by the respective U.S. authorities. gTLDs are subclassified into sponsored top-level domains (sTLD), e.g. .aero, .coop and .museum, and unsponsored top-level domains (uTLD), e.g. .biz, .info, and .name. infrastructure top-level domains (iTLD): The top-level domain .arpa is the only confirmed one. .root has been known to exist without reason.

Domain Tasting Target of US Federal Cybersquatting Lawsuit

So Domain Tasting, where registrants (who may also be registrars) taste names and keep only those that have economic value, is now the target of a federal cybersquatting lawsuit, brought about by lawyers for major brand name retailers Neiman Marcus and Bergdorf Goodman against major domain name registrar Dotster. This Dotster lawsuit involves allegations of cybersquatting by registrars who use the Create Grace Period, which is mandated by ICANN for global registries... more»

Ask Vint Cerf: The Road Ahead for Top-Level Domains

As most readers are no doubt aware, when it comes to the topic of Top-Level Domains (TLDs), Internet Corporation for Assigned Names and Numbers (ICANN) takes center stage. Vint Cerf, Google's VP and Chief Internet Evangelist, who has served as chairman of the board of ICANN since the November of 1999 has accepted CircleID's invitation to directly respond to your questions on the topic. This is your opportunity to have your Top-Level Domain related questions responded by Vint Cerf. more»

Nation of Cameroon Typo-Squats the Entire .com Space

The .cm (Cameroon) ccTLD operators have discovered that since their TLD is simply one omitted letter away from .com, that there is a gold mine in the typo traffic that comes their way. Accordingly, Cameroon has now wild-carded its ccTLD and is monetizing the traffic. The upshot is that, if the Neiman Marcus / Dotster lawsuit over 27 domain names was properly characterized as "massive", then the Cameroonians are now going well beyond massive... more»

China's New Domain Names: Lost in Translation

This morning I got a bunch of alarmist messages from friends asking about this English-language People's Daily article titled: China adds top-level domain names. The paragraph that's freaking people out is: "Under the new system, besides "CN", three Chinese TLD names "CN", "COM" and "NET" are temporarily set. It means Internet users don't have to surf the Web via the servers under the management of ICANN..." Not for the first time, it appears that the People's Daily's English translation is very misleading. more»

.XXX as Proposed is Wrong for Families & Kids

On August 23rd, the Internet Governance Project posted a letter Opposing Political Intervention in the Internet's Core Technical Administrative Functions. I disagree. ICANN and Governments should get involved when it comes to protecting children online. Every effort should be made to make it SIMPLE for average parents to let their children run free online without the risk of running across pornography and adult material while doing so. Why continue to let pornographers run free and unchecked on the most exciting tool created in the history of mankind just because they got there first? more»

Why I Am Participating in the ORSN Project

As a long time supporter of the universal namespace operated by IANA, it may come as a surprise that I have joined the Open Root Server Network project (ORSN). I'll try to explain what's going on and what it all means. ...If one of my kids, or anybody anywhere, sits down in front of a web browser and keys in a URL, it ought to just work. They ought to see the same web page that anybody else would see, no matter what country they're in or what their ISP wants or what their local church or government wants. This universality of naming is one of the foundations on which the Internet was built, and it is how the Internet fosters economic growth and social freedoms. It's what makes the Internet different from old Compuserve, old AOL, old MSN, old Minitel, and everything else that has come -- and gone -- before... more»

New Mobile Domain Another Bad Idea

You may have seen a new proposal for a "mobile" top-level domain name for use by something called "mobile users" whatever they are. (The domain will not actually be named .mobile, rumours are they are hoping for a coveted one-letter TLD like .m "to make it easier to type on a mobile phone.) Centuries ago, as trademark law began its evolution, we learned one pretty strong rule about building rules for a name system for commerce, and even for non-commerce.
Nobody should be given ownership of generic terms. Nobody should have ownership rights in a generic word like "apple" -- not Apple Computer, not Apple Records, not the Washington State Apple Growers, not a man named John Apple. more»

Gartner on New Generic Top Level Domains

Gartner, the well known IT consulting company, has published a report on the new top level domains that will appear some time next year. The report totally misses the mark. In a pure US centric vision, it focuses on ".com" as the must-have TLD, totally overlooking the fact that a ".com" is mostly worthless e.g. in Germany, where ".de" is the TLD one must have to succeed locally... more»

Shambles at the .Pro Registry

Registration of .Pro domains has descended into shambles as the Registry responsible for their administration has allowed a flood of domain registrations which appear to be in breach of the strict rules restricting who can register a .pro domain and the certified credentials required before any such domain can work. more»

ICANN Violating Free Enterprise?

Message to ICANN: Let those who want to create a TLD, simply register it with ICANN. If the TLD is not already taken, if they have the technical capability to mange the TLD, and they have the desire to market domain names on that TLD, then let them do so. ...Do you present a businesss plan to the city you live in before they allow you a business license? Does the city ask you to prove you are financially stable before issuing you a business license? If you apply for a business license to open a clothing store, does the city ask how you will run your clothing store or if you have the necessary expertise to run a clothing store? Does the city think you will hurt them economically if your clothing store goes out of business? No, it's none of their business... more»

How India's .IN Domain Rouses from its Slumber

India is one of the world's fastest growing economies, the global leader in outsourcing and the service computing, and home to over a billion people. But when I first met officials from the Indian government to discuss their plans for .IN, India had a total of just about 7,000 .IN registrations, fewer than most small countries have. ...(Compare to 100,000 names registered last month alone) This is one of the most rapid starts of any domain worldwide. In my conversations with senior officials of the Indian Government and the National Internet Exchange of India (NIXI) which manages the .IN Registry, they credited three key decisions that proved critical to the success of the domain's re-launch... more»

Why Restricted TLDs Should Not Be Gatecrashed

In recent weeks, thousands of what ICANN describes as "questionable" registrations have been activated... Let me illustrate: Mr. ICANN decides to hold a party. He has decided that he only wants to ask some of his professional friends to come, so they are asked to bring their party invites with them to prove they've been invited, because poor Mr. ICANN has had trouble before with people gatecrashing his parties. At a sunrise party he'd held a few years ago, all kinds of people had gatecrashed and no-one had asked to see their invites and it was dreadful. So Mr. ICANN hires a bouncer to stand guard at the front door of his house. The bouncer, Johnny Registry, assures Mr. ICANN that no-one will get in without an invite... more»

ICANN Confirms: Tiered Pricing Not Forbidden in New .BIZ, .INFO and .ORG Contracts

I finally got the "official" word from Vint Cerf of ICANN, "on the record", who confirmed that my interpretation is correct, that differential/tiered pricing on a domain-by-domain basis would not be forbidden under the .biz/info/org proposed contracts. This means that the registries could charge $100,000/yr for sex.biz, $25,000/yr for movies.org, etc. if they wanted to -- it would not be forbidden the way the proposed contracts are currently written. This would represent a powerful pricing weapon for registries, and a fundamental shift in possible domain name pricing, that could lead them to emulate .tv-style price schedules. It doesn't mean they will necessarily do it, but it's not forbidden. When a contract doesn't forbid something bad, it implicitly allows it... more»

OpenDNS: It's Not SiteFinder for Obvious Reasons

The first salvo on NANOG this morning in response to the launch of OpenDNS was a predictable lambasting along the lines of "here comes SiteFinder II". Fortunately the follow-ups were quick to point out that OpenDNS was a far cry from SiteFinder for the obvious reason that people have the choice to use it, nobody had a choice with SiteFinder. ...the real magic here can come from it's use in phishing mitigation. more»

XXX Comes to a Head

Just when you thought the .xxx affair couldn't get any worse, it does. I'm beginning to think that ICANN's approach to TLD approval was cooked up by a demented sergeant from Abu Ghraib... Now, after the triple x people negotiated with ICANN's staff a contract that met all prior objections, and heads into what should be its final approval, word is that a few ICANN Board members are leaning in a negative direction. What is the reason? A group of pornographers has organized a campaign against .xxx, flooding ICANN's comment box with overwhelmingly negative remarks. more»

.ORG Applauds US Government on DNSSEC

.ORG applauds the US Government's decision last week to require all users of the .GOV domain to implement DNSSEC, and even more importantly, to sign the .GOV root. .ORG is the first generic Top Level Domain authorized by ICANN to implement DNSSEC, and we are hard at work putting together a comprehensive plan to roll it out. ›››

The Internet as a Democratic Utility

In the wake of our recent news that .ORG has officially registered 7 million domains, some comments made to CNN by Craigslist founder Craig Newmark this week really resonated with me. The article, entitled "Internet Can Strengthen Democracy" discusses many of the same issues we have found to be the driving forces behind .ORG's consistent year-over-year growth -- community building, interaction, and inclusivity. ›››

Attacks on the security of the Internet have been much in the news lately, and there is an increased urgency to take the technical steps to combat these attacks. .ORG has been doing its part to lead this process by taking introductory steps to implement DNSSEC (Domain Name System Security Extensions)... In order to make DNSSEC effective, there is one additional step that is needed -- "signing the root". ›››
