SITE.su is an online marketplace specializing in premium domain names, with more than 40,000 listings across the .ru, .su, and .рф zones. Customers can search its catalogue by keywords or other parameters, view domain details, and download the full list for review in Excel. Listings include information such as price, age, and search-related indicators, helping visitors assess a domain’s potential.

The marketplace offers both immediate purchases and domain rentals. A purchase transfers the rights to administer the domain, while a rental lets the customer assign their own DNS servers. Rental agreements include priority rights to buy the domain during the rental period, with the purchase price fixed in the agreement; contracts can last up to 50 months. Customers can place orders online, ask questions about a particular domain, or propose a price. SITE.su also provides a help section with contact information and online chat.
