Extension - su

The top-level domain (.su) is allocated to the Soviet Union (Union of Soviet Socialist Republics, USSR), a former federation of socialist states in Eastern Europe and Northern Asia. This TLD was originally intended for websites and internet addresses related to the Soviet Union. The .su domain served as a means to represent and identify the online presence of this former nation. Despite the dissolution of the Soviet Union in 1991, the .su domain is still active but is considered outdated. It is primarily used for websites and internet addresses related to the former Soviet republics, maintaining a continuing role in the online world.
