The top-level domain (TLD) “XN—P1AI” is an internationalized country code (ccTLD). This type of domain is unique in that it uses a language-specific script or alphabet, in this case the Cyrillic script, rather than the Latin alphabet used in most Internet DNS (domain name system) names. This kind of ccTLD is encoded in ASCII characters for compatibility with the domain name system. This particular ccTLD “XN—P1AI” is assigned to Russia as an equivalent to .ru in Cyrillic.
‘P1ai’ corresponds to ‘рф’, which stands for Russian Federation in the Cyrillic script. Introduced in 2010, this domain provides a way for Russian-speaking users to navigate the web in their native script, fostering better usability and accessibility. According to a report from Eurid, by 2012, “рф” had become the most successful internationalised ccTLD (source: “The World Report on Internationalised Domain Names Deployment 2012”, by EURid-UNESCO).
Companies and individuals seeking to reach a predominantly Russian-speaking audience might prefer to use an .рф domain. Their use has been widely adopted among Russian businesses. For example, internet giant Yandex opted for яндекс.рф, and Russia’s state-owned Television and Radio Broadcasting Company uses вгтрк.рф.
There are some restrictions on registering .рф domains: the registrar must be accredited by the domain’s administering body, the Coordination Center for TLD RU/РФ, and domain names can only contain letters from the Cyrillic alphabet. There’s also a mandated process for resolving domain disputes, as stipulated by the Policy of the .RU and .РФ ccTLDs Dispute Resolution.
The ‘XN—’ designates that the ccTLD uses the Punycode encoding method to represent Unicode within the limited character set allowed in the DNS. Punycode was established by a working group in the Internet Engineering Task Force and set out in RFC 3492. It’s a necessary mechanism for ‘translating’ non-Latin scripts into a form that can be entered into the DNS (source: RFC 3492, “Punycode: A Bootstring encoding of Unicode for Internationalized Domain Names in Applications (IDNA)”).
In conclusion, the TLD “XN—P1AI” represents an effort to make the Internet more accessible to users worldwide, by breaking the dominance of Latin scripts in web addresses and permitting people to browse, create, and share content in their native scripts.
