SITE.su is an online marketplace specializing in premium domain names, with a catalogue of more than 40,000 domains, primarily in the .ru, .su, and .рф zones. The service enables customers to browse listings, search by keywords or other parameters, and purchase or rent domains online. Purchases are completed with the transfer of domain administration rights, while rental provides the right to use the domain by assigning the customer’s DNS servers. Rental agreements include a priority right to buy the domain at a price fixed in the contract and can run for up to 50 months.

Listings display purchase and monthly rental prices, and may include domain age and search-related indicators. Customers can view or download the full domain catalogue, including data such as TIC and PR, and submit questions or price offers through the site. SITE.su also provides a help section and online chat for customer inquiries. By combining searchable listings, immediate online transactions, and flexible purchase or rental options, the marketplace serves businesses and individuals seeking a domain for a website or online project.
