SITE.SU is an online marketplace for premium domain names, offering more than 39,000 domains across the .ru, .su, and .рф zones. The service helps businesses, entrepreneurs, and other project owners find domain names that match their brand, keywords, or market. Customers can browse the full inventory, download a domain list, or use advanced search to explore available options.

Domains are available for immediate online purchase or monthly rental. A purchase transfers administrative rights to the buyer, while rental involves assigning the customer’s DNS servers and includes a contractual priority right to buy the domain during the rental period. Listings display purchase and rental prices, and may also include domain age and search-related statistics. Customers can submit questions or suggest a price for a specific domain, with contact options and online chat available through the Help section. The marketplace presents related and translated domain suggestions to support comparison and discovery, making it easier to evaluate alternatives before choosing a name for a website or business.
