The top-level domain (TLD) XN—J1AEF is a unique string of characters that is used in the Domain Name System (DNS) of the internet to identify specific websites. For context, some common TLDs you may be aware of include .com, .net, and .org.
Every TLD is part of the larger DNS, a global network coordinated by the Internet Corporation for Assigned Names and Numbers (ICANN). This system helps facilitate the smooth operation of the internet by enabling people to reach specific websites by typing in their associated domain names instead of their numerical IP addresses, which are harder for most people to remember.
The XN—J1AEF, like all TLDs, has two important parts: the “xn—” prefix and the “j1aef” identifier. The “xn—” prefix is a standard indicator that the TLD uses Punycode—a special encoding system used for converting Unicode strings into unique ASCII character formats that are compatible with the DNS. This typically indicates that a TLD is a part of Internationalized Domain Names (IDNs), which allows domain names in non-Latin alphabets (like Arabic, Cyrillic, or Chinese).
The “j1aef” identifier is the Punycode representation of the string that forms the TLD. In this particular case, “j1aef” is the Punycode for “киев,” which translates to “Kiev” in English and is the capital of Ukraine.
It’s worth noting that ICANN implemented the IDNs system in 2003, aiming to make the internet more globally accessible by allowing domain names in different languages and scripts. In terms of the sources used to construct this answer, the information is available from several reliable and recognized organizations, including ICANN and the Internet Assigned Numbers Authority (IANA).
ICANN is the international organization that manages DNS and releases new TLDs to ensure that every IP address and domain name in the world is unique. IANA, as part of ICANN, is a department that oversees global IP address allocation, DNS root zone management, and other Internet protocol resources.

In summary, XN—J1AEF is a unique TLD, part of the Internationalized Domain Name, and represents the city “Kiev” in the Cyrillic alphabet. It’s part of a broader effort to make the internet more globally accessible by allowing domain names from non-Latin alphabets.
