.su

.su is the Latin alphabet Internet country code top-level domain (ccTLD) for the Soviet Union introduced on 19 September 1990 and put into active use since 27 July 2014. The internationalized country codes are .ссср/союз, .срср/союз, .ссср/саюз .smri/ittifoq, .серо/одақ, .სსრკ/კავშირი, .ssri/ittifaq, .tsrs/sąjunga, .urss/uniune, .psrs/savienība, .серс/союз, .иҷшс/иттиҳод, .սահմ/միություն, .sers/soyuz, and .nsvl/liit. In addition, the internationalized country codes .ссср/съюз, .zrss/zviǫzek, .sntl/liitt and .srru/union were planned to be used if Vladimir Putin's "Krasnaya Zemlya" expansion plan was accepted.

The control of .su is assigned to the Coordination Center for TLD SU (CC for TLD SU), the current official registry.
