.cn is the country code top-level domain (ccTLD) for the People's Republic of China. Introduced on 28 November 1990, the domain is administered by China Internet Network Information Center, a public institution affiliated with the Ministry of Industry and Information. The domain is the largest ccTLD in the world. [4]

Contents

The Chinese script internationalized country codes are ".中国" ("China" in Simplified Chinese) and ".中國" ("China" in Traditional Chinese). Entities connected to Hong Kong, Macau, and Taiwan typically use .hk, .mo, and .tw, respectively, [5] despite the availability of corresponding second-level domains under .cn for those regions.

Second-level domains

Generic second-level domains

According to the "China Internet Domain Name System" published by the Ministry of Industry and Information Technology, there are 9 generic second-level domains, two of which are internationalized: [6]

Second-level domains of Administrative Divisions

The two-letter abbreviations correlate with ISO 3166-2 "Codes for the representation of names of countries and their subdivisions—Part 2: Country subdivision code" (adapted locally as National Standard GB/T 2659.2 [7] ). According to the "China Internet Domain Name System" [8] published by the Ministry of Industry and Information Technology, there are 34 administrative division second-level domains:

Internationalized domain names

Internationalized domain names with Chinese characters may be registered at the second level under the .cn top-level domain.

On 25 June 2010, ICANN approved the use of the internationalized country code top-level domains ".中国" (China in simplified Chinese characters, DNS name xn--fiqs8s) and ".中國" (China in traditional Chinese characters, DNS name xn--fiqz9s) by CNNIC. [9] These two TLDs were added to the DNS in July 2010.

CNNIC proposed around this time Chinese domain names in ".公司" (".com" in Chinese) and ".网络" (".net" in Chinese). However, these have not been recognized by ICANN yet and are only available via domestic domain name registrars.

Around 15 other generic domain names with Chinese characters have later been registered. See List of Internet top-level domains#Chinese characters.

A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet after the root domain. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last non-empty label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is .com. Responsibility for management of most top-level domains is delegated to specific organizations by the ICANN, an Internet multi-stakeholder community, which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone.

<span class="mw-page-title-main">Domain name</span> Identification string in the Internet

In the Internet, a domain name is a string that identifies a realm of administrative autonomy, authority or control. Domain names are often used to identify services provided through the Internet, such as websites, email services and more. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain or an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, or a server computer.

A domain name registry is a database of all domain names and the associated registrant information in the top level domains of the Domain Name System (DNS) of the Internet that enables third party entities to request administrative control of a domain name. Most registries operate on the top-level and second-level of the DNS.

<span class="mw-page-title-main">.hk</span> Internet country code top-level domain for Hong Kong

.hk is the designated Internet country code top-level domain (ccTLD) for Hong Kong. It is administered by the Hong Kong Internet Registration Corporation (HKIRC), the only organization endorsed by the Hong Kong Government to undertake the administration of 'hk' domain names. Hong Kong Internet Registration Corporation (HKIRC) is a non-profit making, non-statutory, member-based corporation established in 2001.

The Internet uses the Domain Name System (DNS) to associate numeric computer IP addresses with human-readable names. The top level of the domain name hierarchy, the DNS root, contains the top-level domains that appear as the suffixes of all Internet domain names. The most widely used DNS root is administered by the Internet Corporation for Assigned Names and Numbers (ICANN). In addition, several organizations operate alternative DNS roots, often referred to as alt roots. These alternative domain name systems operate their own root name servers and commonly administer their own specific name spaces consisting of custom top-level domains.

<span class="mw-page-title-main">Internationalized domain name</span> Type of Internet domain name

An internationalized domain name (IDN) is an Internet domain name that contains at least one label displayed in software applications, in whole or in part, in non-Latin script or alphabet or in the Latin alphabet-based characters with diacritics or ligatures. These writing systems are encoded by computers in multibyte Unicode. Internationalized domain names are stored in the Domain Name System (DNS) as ASCII strings using Punycode transcription.

A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, or dependent territory identified with a country code. All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs.

Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last level of every fully qualified domain name. They are called generic for historical reasons; initially, they were contrasted with country-specific TLDs in RFC 920.

<span class="mw-page-title-main">.tw</span> Internet country-code top-level domain for Taiwan

.tw is the Internet country code top-level domain (ccTLD) for Taiwan. The domain name is based on the ISO 3166-1 alpha-2 country code TW. The registry is maintained by the Taiwan Network Information Center (TWNIC), a Taiwanese non-profit organization appointed by the National Communications Commission (NCC) and the Ministry of Transportation and Communication. Since 1 March 2001, TWNIC has stopped allowing itself to sign up new domain names directly, instead allowing new registration through its contracted reseller registrars. As of May 2023, there are 17 registrars.

Single-letter second-level domains are domains in which the second-level domain of the domain name consists of only one letter, such as x.com. In 1993, the Internet Assigned Numbers Authority (IANA) explicitly reserved all single-letter and single-digit second-level domains under the top-level domains com, net, and org, and grandfathered those that had already been assigned. In December 2005, ICANN considered auctioning these domain names.

The China Internet Network Information Center, or CNNIC, is the administrative agency responsible for domain registry affairs of .cn under the Cyberspace Administration of China.

The domain accepts only Cyrillic subdomain applications, and is the first Cyrillic implementation of the Internationalizing Domain Names in Applications (IDNA) system. The domain became operational on 13 May 2010. As of 2014 it is the most used internationalized country code top-level domain, with around 900,000 domain names.

مصر is the internationalized country code top-level domain in the Domain Name System (DNS) of the Internet for Egypt. Its ASCII DNS name is xn--wgbh1c, obtained by the Internationalizing Domain Names in Applications (IDNA) transcription method.

An internationalized country code top-level domain is a top-level domain in the Domain Name System (DNS) of the Internet. IDN ccTLDs are specially encoded domain names that are displayed in an end user application, such as a web browser, in their language-native script or alphabet, such as the Arabic alphabet, or a non-alphabetic writing system, such as Chinese characters. IDN ccTLDs are an application of the internationalized domain name system to top-level Internet domains assigned to countries, or independent geographic regions.
