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.

ICANN Paints Itself Into a Corner

ICANN recently commissioned a report from a domain auction company to see whether it would be a good idea to auction Top-Level Domains (TLDs) that have multiple applicants. Remarkably, the domain auctioneers came to the conclusion that auctions are a great idea, which they surely are for some people. But are they a good idea for ICANN? And if ICANN admits they can't evaluate competing applications on their merits, how can they keep the process from turning into another speculative land grab? more»

ICANN to Auction New Generic Top Level Domains

ICANN has just published a paper from its contractor PowerAuctions LLC, regarding the use of auctions to award new Top Level Domains (TLD) strings in case of contention. I can understand what ICANN wants to avoid. In the past, it has been criticized for using the "beauty contest" model with the redelegation of the .net TLD... However, the auction model is based on the idea that whoever wins the auction will be able to recoup its investment on the sale... 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»

Why New TLDs Don't Matter

Lost amid the furor about ICANN's rule change that may (or may not) lead to a flood of TLDs is the uncomfortable fact that almost without exception, the new TLDs created since 2000 have been utter failures. Other than perhaps .cat and .mobi, they've missed their estimates of the number of registrations by orders of magnitude, and they haven't gotten mindshare in the target community. So what went wrong? more»

New Generic Top-Level Domains and Internet Standards

The recent decision by ICANN to start a new round of applications for new generic Top-Level Domains (gTLDs) is launching a round of questions on the IETF side about its consequences. One possible issue may be with vanity gTLDs like apple, ebay etc. Some expect that every Fortune 1,000,000 company will apply for its own TLD. My guess is rather the Fortune 1,000 for a start, but this does not change the nature of the issue, i.e. those companies may want to use email addresses like user@tld. more»

ICANN's New gTLD Process: Hype and Reality

At its 32d International Junket Meeting last week, ICANN's Board approved the GNSO Council's recommendations for the eventual addition to the root of new generic top-level domains (gTLDs). This means that eventually, when the staff drafts, community comments upon, and Board approves implementation processes, those with deep pockets will have the opportunity to bid for new TLD strings... more»

The SocialDNS Project… and Why DNS is Not the Phone Book of the Internet

In this article I will explain the motivations behind the SocialDNS Project. I will justify why the DNS system is NOT the phone book of the Internet. More concretely, DNS is not a public directory nor enables search mechanisms over meta-information related to domains. In this line, I will present the advantages of SocialDNS, a naming and directory system that aims to become the phone book of the Web. SocialDNS is NOT another alternative DNS root nor aims to replace the current DNS for resolving domain names. It complements the existing DNS to offer advanced services that are beyond the scope of the existing infrastructure for Web settings. more»

ICANN to Add New Top-Level Domains, World to Come to an End

The biggest buzz from the Paris ICANN meeting was that the board accepted last fall's proposal for a streamlined process to add new TLDs. A variety of articles in the mainstream press, many featuring inflammatory but poorly informed quotes (from people who probably got a phone call saying "We go to press in five minutes, what do you think about ICANN's plan to add a million new domains?") didn't help. When can we expect the flood of TLDs? Don't hold your breath... more»

Why New TLDs Don't Change a Thing

I have a heard a lot lately about ICANN unanimously voting in favor or relaxing top level domain rules and had a few people come to me and ask 'how does that affect what you do?' The short answer is, it won't; at least not for a long time and here is why... There might be some huge potential gain if all shoe companies got .shoes and branded it, but someone would have to manage it and each would have to spend money to brand .shoes to consumers. Adidas gets adidas.shoes but spends nothing to brand it and lets Nike pay to brand .shoes and Reebok to brand it as well and leech. So instead of cartel like behavior (which is hard to maintain), we fall back into .com more»

ICANN Takes First Step to Becoming a Global Content Regulator

There has been wide coverage of ICANN's decision this week to adopt a new process for creating new global Top Level Domains (gTLDs). Publishing a clear, transparent and objective process is thought likely to result in a considerable expansion of gTLDs -- although nobody really knows whether this means "quite a lot" or "many thousands"... Less attention has been given to one of the new tests ICANN will use when considering whether to approve a new gTLD, contained in GNSO's sixth recommendation... more»
