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.

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»
During the 2+ weeks for which Site Finder was operational, a number of ISPs took steps to disable the service. A study just released reveals details and analysis, including specific networks disabling Site Finder during its operational period. For example, China blocked the traffic at its backbone, and Taiwan's Chunghwa Telecom and Korea's DACOM also disabled the service. US ISPs seem to have been slower to act, in general -- but US ISP Adelphia disabled the service September 20-22 before re-enabling it on September 23. more»
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»
In an RFC prepared by Donald E. Eastlake 3rd and Declan McCullagh, an analysis is offered for proposals to mandate the use of a special top level name or an IP address bit to flag "adult" or "unsafe" material or the like. This document explains why these ideas are ill considered from legal, philosophical, and technical points of view: "Besides technical impossibility, such a mandate would be an illegal forcing of speech in some jurisdictions, as well as cause severe linguistic problems for domain or other character string names." more»
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»
A number of people, notably Viviane Reding, the European Commissioner for Information Society and Media, have been asking about how to Break The Internet. Since Mme Reding seems to have absolutely no prior experience in the Information Technology, Computing or Telecommunications industries, I have prepared this brief HOWTO. "1. Declare the creation of a new Root Zone. This is the easy bit - all you have to do is spout great volumes of hot air at a conference in Geneva, and then storm out in a huff when other people refuse to take you seriously. Then you get the PFY who services your photocopier to declare the creation of a new European Root Zone! Hooray!" more»
There soon will be a central place for Web surfers to dwell in a forbidden cyber land of adult fantasies, sex, dark rituals and total taboos. Finally, ICANN has given in to the pressure and has tossed a big rock across the turbulent e-commerce ocean. It has approved a new suffix, .xxx, for adult-only porn sites, creating ripples and debates in ever so confusing global cyber branding times when cyber global domain name challenges are being fought in the complex earthly trademark realities. Three things are bound to happen... more»
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»
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»
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»
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»
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»
We, as the Internet engineering community, have made a great mistake. Actually, it wasn't even one large mistake, but a series of small ones. Engineers are busy people, and most of us work under the constraints of the organizational entities we serve (be it ISPs, non-internet corporates, or even non-profits). Few of us have time for politics; even fewer have the desire and motivation for politics, and those of us who do try usually end up facing a brick wall of stubbornness, lack of understanding of the underlying technical issues, or just a deaf ear. more»
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»
So-called domain tasting is one of the more unpleasant developments in the domain business in the past year. Domain speculators are registering millions of domains without paying for them, in a business model not unlike running a condiment business by visiting every fast food restaurant in town and scooping up all of the ketchup packets. Since 2003, the contract between ICANN and each unsponsored TLD registry (.biz, .com, .info, .net, .org, and .pro) has added an Add Grace Period (AGP) of five days during which a registrant can delete a newly registered domain and get a full refund. Although this provision was clearly intended to allow registrars to correct the occasional typo and spelling error in registrations, speculators realized that this allows them to try out any domain for five days for free... more»
.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. ›››
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. ›››
.ORG, The Public Interest Registry, the registry behind the global .ORG domain name, announced today that more than 7 million domain names are now registered as .ORG, making it the third largest generic domain (after .com and .net). Since management of the registry was assumed by Public Interest Registry in 2003, .ORG registrations have increased more than 250%. ›››
On July 29, the Non-Commercial Users Constituency (NCUC) and Public Interest Registry (PIR) sent out a joint letter to ICANN asking it to consider the interests of the end-users as core to its policies in Internationalized Domain Names (IDN) implementation... As of today's date, August 21, 2008, we have yet to receive even an acknowledgement of receipt of our letter... ›››

Hostway Corporation, the global Web solutions leader, announced it is now taking reservations for the .Pro Top Level Domain (TLD) through August 31, 2008. Hostway's wholly owned subsidiary, RegistryPro, is the exclusive Internet registry for .Pro, a TLD for licensed professionals and entities. ›››
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". ›››
dotMobi, the consortium behind .mobi, the only Internet address created specifically for finding Web sites that work on mobile phones, today announced the launch of ringtones.mobi, a site that makes it easier for music fans to buy ringtones and mobile-friendly wallpaper images from independent and established music acts. ›››
