SITE.su is an online marketplace for premium domain names, offering a catalog of more than 40,000 domains, primarily in the .ru, .su and .рф zones. The service helps businesses and individuals find domain names for websites and online projects, with search tools for matching terms, prefixes and related transliterations. Visitors can browse the full inventory, use advanced search, or download a domain list with information such as age and ratings.

Domains are available for immediate purchase or monthly rental. A purchase transfers domain administration rights online, while rental allows the customer to assign their own DNS servers. Rental agreements include priority rights to buy the domain at a price fixed in the contract, and can run for up to 50 months. SITE.su also provides domain-specific inquiries and price offers through its help section, alongside registration, account access and online assistance. Its listings display purchase and rental prices and may include indicators intended to help assess a domain’s search visibility and potential value.
