.yu is the Internet country code top-level domain (ccTLD) assigned to Yugoslavia.
The .yu domain is administered by the YUNET Association, an organization based in the Faculty of Electrical Engineering at the University of Belgrade. ICANN has resolved that .yu will operate temporarily under the Serbian National Register of Internet Domain Names, operators of the new .rs domain registry, during transition until its eventual abolition on or before 30 September 2009.
This allows a two-year transition period for existing .yu names to be transferred either to .me (which is to be delegated to the Government of Montenegro) or to .rs (for Serbian domains). It is one of the few ccTLDs that does not correspond to a curent ISO 3166-1 two-letter code.
The code YU was replaced by CS in July 2003 following the official name change from Federal Republic of Yugoslavia to Serbia and Montenegro in February 2003. The ccTLD .cs was reserved for Serbia and Montenegro after the name change of February 2003, but was never actually used.
In September 2006, ISO proposed .rs for Serbia and .me for Montenegro. On September 26, 2006 the ISO 3166 Maintenance Agency agreed on the change of ISO 3166-1 Alpha-2 code CS to RS.
Background Information :
Yugoslavia (Serbo-Croatian, Bosnian, Croatian, Serbian, Montenegrin, Slovene, Macedonian: Jugoslavija; Cyrillic script: ÏêÒâÏþÏ¾ÒüÏ©ÏÏÏ¹ÒÿÏ; literally in English: "South Slavia" or "Land of South Slavs") is a term that describes three political entities that existed successively on the Balkan Peninsula in Europe, during most of the 20th century.
The first country to be known by this name was the Kingdom of Yugoslavia, which before 3 October 1929 was known as the Kingdom of Serbs, Croats and Slovenes. It was established on 1 December 1918 by the union of the State of Slovenes, Croats and Serbs and the Kingdom of Serbia. It was invaded by the Axis powers in 1941, and because of the events that followed, was officially abolished in 1945.
