SITE.su is an online marketplace for premium domain names, offering more than 40,000 domains across the .ru, .su, and .рф zones. The service enables customers to browse available names, search by keywords or other parameters, and view listings with purchase and rental prices. Domains can be bought online, with ownership administration transferred immediately, or rented by assigning the customer’s DNS servers. Rental agreements include a priority right to purchase the domain during the rental term, with the buyout price fixed in the contract. The stated maximum rental agreement period is 50 months.

SITE.su provides tools to view or download its domain catalogue, including a spreadsheet option, and offers contact support and online chat through its Help section. Listings may include domain age and a rating based on search-related indicators. For example, taiexpress.ru appears among the available listings with separate prices for purchase and monthly rental. Customers can also send an inquiry or propose a price for a domain.
