all you need to know about domain names
(and some you don't need to know, but is interesting anyway)
CHAPTER 1.02
WHO RUNS THE SYSTEM?
The Internet Corporation for Assigned Names and Numbers (ICANN) is responsible for a range of technical aspects of the internet, including the co-ordination of the assignment of domain names. The Domain Name System (DNS) allows for the registration of domain names within a number of registries known as 'top level domains' (TLDs). TLDs fall into two broad categories:
* Generic top-level domains (gTLDs) eg .com * Country code top-level domains (ccTLDs), such as .uk for the United Kingdom and .au for Australia.
Each country has its own naming authority which runs the domain name system for that country. For example, in the USA the regulating agency is the Internic (internic.net), the UK's ccTLD registry is owned and operated by Nominet UK (nic.uk), France's is AFNIC (nic.fr), Germany's DENIC (denic.de) and Canada's CIRA (cira.ca). The majority of these are not-for-profit companies or public sector organizations (eg universities). A full list of ccTLDs and their sponsoring organizations is available on the website of the Internet assigned numbers authority (IANA) - go to iana.org and follow the link on it's the homepage to 'database of Top Level Domains'.
To register a name you must apply to the relevant authority for 'permission' to use that name. It is rare, however, for a user to actually use the naming agencies directly, it being more likely that they will use intermediaries - 'registrars' (or 'registration agents') - to register their domain name. It is also the case that although you might own a domain name that agency retains the authority to withdraw it from use on the Internet - making it, effectively, useless. It is also worth noting that although you might have registered your domain name - and so own it - such is the system that if you don't renew its registration on an annual basis that registration expires and, eventually, the name is made available on the free market - often by auction. Although it is possible to pay these annual fees for years in advance, this can result in the renewal being forgotten some years down the line.
Although the owner of a domain name that might be copyrighted or trademarked can seek to recover the 'dropped' name by appealing to an arbitration panel under ICANN's dispute-resolution policy (more of this in the legal aspects chapter), the practice of drop catching breaks no laws and so might be considered a legitimate business model.
