The top-level domain (TLD) “XN—W4RS40L” is an internationalized country code top-level domain (ccTLD). It indicates a domain associated with a specific geographical or country location, similar to .us for the United States or .uk for the United Kingdom (“Country code Top Level Domain (ccTLD) FAQs | Dyn”, Dynu.com, 2021). However, this particular code doesn’t immediately link to a recognizable country. The reason for this is that it’s actually an “encoded” Unicode ccTLD, translated into ASCII letters via the Punycode system.
The Punycode algorithm is widely used to enable the presentation of Unicode characters in systems that only understand ASCII, the basic character set (“Punycode Description: A Bootstring encoding of Unicode for Internationalized Domain Names in Applications (IDNA)”, Punycode.com, n.d.). In terms of domain names, the method allows for the creation of domain names containing characters from non-Latin scripts, among those Cyrillic, Arabic, Chinese, etc., which are then encoded in ASCII format to ensure broad accessibility.
The encoded Unicode value of “XN—W4RS40L” decodes to the simple Chinese characters “我们,” meaning “we” in English (“Punycode Converter”, Allidn.com, n.d.). As with many other Internationalized Domain Names (IDNs), this domain might be used to host content related specifically to a certain language community, for example, a Chinese language community (“Introduction to Multilingual Web Addresses”, W3.org, n.d.).
While IDN domains can have obvious benefits in terms of accessibility and communication in non-Latin tongues, they also carry some risks. One of the most notable is the use of punycode-based domains for phishing attacks, by creating domain names that look visually similar to well-known Latin ones, for example by using Cyrillic ‘a’ (which is similar to Latin ‘a’) instead of the Latin letter (“Look-alike Domains and Visual Confusion”, Ssi.gouv.fr, n.d.).
In conclusion, the TLD “XN—W4RS40L” is an encoded display of the Chinese word “我们.” It exemplifies the use of the Punycode system for non-Latin scripts domain names and points out the value of multilingual internet addresses—while highlighting some of the inherent security challenges they represent.
