The top-level domain (TLD), “XN—GCKR3F0F”, is an internationalized domain name (IDN) TLD, specifically in the Punycode encoding format. Punycode is a way to represent international characters in ASCII format, which is the accepted standard for internet hosts. It’s used mainly for domain names with non-Latin alphabets, such as Arabic, Chinese, Cyrillic, and others.
The translation of “XN—GCKR3F0F” from Punycode to Unicode is “ドメイン” which is a Japanese term for “domain”. Therefore, this TLD is a part of the Internationalizing Domain Names in Applications (IDNA) system, which was designed to enable the use of more characters than just ASCII in domain names.
In reference to “XN—GCKR3F0F”, the prefix “xn—” signifies that the domain name uses Punycode representation. This specific format was established by the Internet Engineering Task Force (IETF) to overcome the problem of writing domain names in scripts that are not ASCII-based. The protocol of IDNA was established to address the issue of incorporating international characters in the domain name system (DNS), as described in RFC 3490 (Internet Engineering Task Force, 2003).
An example of a website that might use the TLD “XN—GCKR3F0F” could be a Japanese-based or Japanese-language site. This TLD’s Unicode representation, “ドメイン” is utilized by Japanese-speaking web users. It expands the accessibility and usability of the internet by liberating non-Latin script users from having to use a language that is not their own to access websites.
We can take ‘Verisign’ as a recognized source that keeps records of all existing TLD. According to the record by Verisign, “XN—GCKR3F0F” is in their root zone database as a delegated string, indicating it is an authorized internationalized TLD.
Moreover, the Internet Corporation for Assigned Names and Numbers (ICANN) also recognizes and regulates the registration process regarding these IDNs to maintain the Internet’s stability and security. To get such a domain, registrants must go through authorized registrars.
This Punycode system, despite its apparent complexity, is essential for creating a more inclusive and globally accessible internet. By enabling the use of non-LCIS scripts in domain names, Internet users worldwide can navigate the web in their own language, making the Internet a truly global network.
Thus, to conclude, “XN—GCKR3F0F” is the Punycode representation of the word “ドメイン”, a Japanese term meaning “domain”.
