The control of .ru is assigned to the Coordination Center for TLD RU (CC for TLD RU), the current official registry. On 1 January 2005 the former registry Russian Institute for Public Networks (RIPN) has fully stopped to provide operations for registrations directly under .ru but still carries out registry operations for the third-level domain names under .com.ru, .net.ru, .org.ru and .pp.ru.
The company RELCOM also proposes third-level registrations beneath various second-level domains such as .msk.ru (Moscow), while Macomnet Telcom proposes third-level registrations beneath .int.ru simultaneously.
RU-CENTER is one of the accredited registrars in .ru and also handles registration services for .su, the top-level domain of the Soviet Union, which was supposedly going to be phased out given the non-existence of the country it represents, but nevertheless has been accepting new registrations along with .ru. The legal status and ownership of .su is being contested by the ICANN, the Russian government and several Russian commercial entities.
