SITE.su is an online marketplace specializing in premium domain names, offering more than 40,000 options in the .ru, .su, and .рф extensions. Customers can browse, search by keyword or other parameters, and view domain details such as age and search-related indicators. The marketplace serves businesses and individuals seeking a domain for a website or online project.

Domains are available for immediate purchase or monthly rental. A purchase transfers the domain’s administration rights, while rental lets the customer assign their own DNS servers. Rental agreements include a priority right to buy the domain during the contract period, with the purchase price fixed in the agreement; contracts can run for up to 50 months. The site provides online checkout, a full domain list for viewing or download, and a contact form for questions or price offers. Help and online chat are available through its support section. SITE.su presents domain listings with prices in rubles and information intended to help visitors compare names and choose an option suited to their needs.
