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, the Russian Institute for Public Networks (RIPN), stopped new registrations directly under .ru, but still carried out registry operations for domain names under the second-level domains .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.
