.xk is a temporary, unofficial country code top-level domain for Kosovo, assigned under the United Nations Security Council Resolution 1244 in 1999.[1]

XK falls under the ISO 3166-1 "alpha-2 user-assigned codes", which include AA, ZZ, QM to QZ and XA to XZ.[2] 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.[3][4][failed verification] 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the latter may not be chosen due to its possible use for a reunified Korea, if South Korea's current domain, .kr, is superseded).
