Although the Soviet Union was dissolved at the end of 1991, it is still possible to register addresses under .su, with administration being taken over by the successor state Russia. The ICANN plans to top-level domain dissolve with time and delete, but lobbyists are fighting to preserve the top-level domain . In 2008 the fees for .su domains were massively reduced in order to make them more attractive compared to .ru and to strengthen the position vis-à-vis ICANN.
In November 2011 there were around 100,000 .su domains. In October 2012 almost 110,000 .su domains were registered, and according to statistics from Russian Domains, around 2,500 addresses are added every month .
Since the end of 2011, a copy of your ID has been required to register a .su domain. This requirement does not apply to owners of an existing address or its renewal. However, it has resulted in numerous registrars no longer offering .su domains. Addresses are only registered on the second level; in addition to the Latin script, internationalized domain names in Cyrillic script are also permitted.
