Every web page has an Internet address. The termination of this address is called a top-level domain (TLD). The country code Top Level Domains (ccTLD) , in Spanish country code top level domain, refer to a specific country or region (for example .es for Spain or .eu for the European Union), so they are also known as geographic domains .
The fundamental assignment of all ccTLDs is managed by ICANN (Internet Corporation for Assigned Names and Numbers) . However, the administration and registration of these domains is in the hands of the NIC (Network Information Center, also called Domain Name Registry) of each country; for example, in Spain it is Red.es and in Mexico Registry .MX. There are currently more than 200 ccTLDs. Here is a list of all these top level domains with some of their most important features.
The characteristics of ccTLDs
Country-specific extensions refer to the language-speaking region or territory for which the content of a web page is intended. Country-specific domains are always made up of two letters of the Latin alphabet. The only exceptions are the so-called internationalized domain names (IDN ccTLDs) of some countries . These country domains are characterized in that in addition to the traditional ccTLD, they have one or two variants of it in a language that does not use the letters of the Latin alphabet. A classic example is the ccTLDs of Sri Lanka, where in addition to . lk there are also the TLDs ලංකා and . இலங்கை, which refer to the island state in the Sinhala and Tamil languages respectively.
Inappropriate uses of ccTLDs
The counterpart to ccTLDs are generic top-level domains (gTLDs) that are not region-related but topic-related (such as .com for commercial/enterprise or .org for organizations) and can be made up of more than two letters. However, some ccTLDs are used for other purposes, for example, in a similar way to gTLDs, for the designation of certain types of web pages or the theme of an online project. Linguistic games with geographic top-level domains are common. Some examples of this include:
- Ftbl.tv – This links website and part Livestream Channel reports on all things football, broadcasts matches from around the world and uses the Tuvalu ccTLD . The extension . tv is very popular, especially in the field of streaming portals (TV, movies and videos).
- Espana.fm: the web address of a platform that brings together the main Spanish-speaking radio stations uses the regional extension belonging to the Federated States of Micronesia . The abbreviation fm also stands for “frequency modulation” and is associated with FM radio. Consequently, the use of the ccTLD . fm is very popular for web radio, audio and podcasts on the Internet as is . tv for video offers.
- Meet.me: Translated into Spanish, this expression means “find me” and is the most expensive domain in Montenegro (it was sold for $450,000). MeetMe is the name of a social network in the United States that, thanks to the ccTLD of Montenegro , was able to completely and cleverly include its brand name in its domain.
- Educ.ar: This online platform is an example of a language game that does not violate the basic principles of country domains. The termination. ar belongs to Argentina, and in this case it has been used by the Argentine Ministry of Education and Sports for the educational portal of this country.
A special case with geographic domains is the . tk . Around 30 million web pages use this ccTLD, despite the fact that the island of Tokelau, associated with this domain, does not even have 2 million inhabitants. Mass registration of web pages. tk is mainly based on the fact that, in the past, it was possible to secure one of these ccTLDs completely free of charge. Even now, the first 12 months are usually free.
The complete list of domains by country
Below is a list of all country-specific domain extensions. In the table there are not only references to the places they belong to, but also to whether or not DNSSEC authentication is possible . The DNSSEC Internet standards can be used by websites to prevent manipulation of the Domain Name System , especially phishing websites that seek to steal private information through fake web pages.
In the last column we show you if you can register Internet addresses with the respective ccTLD that include an internationalized domain name (IDN) . This type of domain extensions can not only be composed of Latin characters, but also allows the inclusion of characters from other alphabets as diacritics in their second level domains (that is, the domain name before the first geographic extension). level). An example of this is the thinkdesign.com page that includes the letter ñ.
As a consequence, top-level domains that have an IDN can add special characters to the already allowed Latin letters, even in the domain name. However, this does not mean that all top level domains are offered at the same time as internationalized ccTLDs , as in the example mentioned above for Sri Lanka. This can be easily cleared up with domain extensions like . is , . mx or . ar , where, although the domain name may include the umlaut (ü) and other letters with diacritical accents (á,é,í,ó,ú) or also the letter “ñ”, the extension (either . es , , .mx or .ar _) must be kept intact. Seen from another perspective, because Spanish uses the Latin alphabet, the internationalization of domains for Spanish-speaking countries is not necessary (unlike the official languages of Sri Lanka).
