.xk is a temporary, unofficial country code top-level domain for Kosovo, assigned under the United Nations Security Council Resolution 1244 in 1999.{{ cite web | url=https://www.cia.gov/the-world-factbook/countries/kosovo/#communications | title=Kosovo - The World Factbook | website=The World Factbook | access-date=2021-04-26 }}

XK falls under the ISO 3166-1 "alpha-2 user-assigned codes", which include AA, ZZ, QM to QZ and XA to XZ.{{ cite web | url=https://tools.ietf.org/id/draft-lewis-user-assigned-tlds-00.txt | title=User Assigned ISO 3166-1 Alpha-2 Codes and the DNS Root Zone | first=E. | last=Lewis | date=2015-03-09 | access-date=2021-04-26 }} This means it is reserved for private use and will not be permanently assigned to any entity – nor used as a country code top-level domain.{{ Cite news | url=https://tools.ietf.org/html/draft-arends-private-use-tld-02 | title=Top-level Domains for Private Internets | first1=R. | last1=Arends | first2=E. | last2=Lewis | newspaper=Ietf Datatracker | date=2020-06-08 | access-date=2021-04-26 }}{{ cite web | url=https://psg.com/~randy/lists/iesg/2003/msg01081.html | title=Results of IANA Selection of IDNA Prefix | quote=The use of ISO 3166-1 the user-assigned elements removes the possibility that the code will duplicate a present or future ccTLD code | date=2003-02-11 | access-date=2021-04-26 }}{{Failed verification|date=October 2022}} Thus, its use is unofficial and temporary, until Kosovo is assigned its own alpha-2 country code, with possible options including .ka, .ks, .kv, and .ko (although the latter may not be chosen due to its possible use for a reunified Korea, if North and South Korea's current domains, .kp and .kr respectively, are superseded).{{original research inline|date=January 2025}}
