SITE.su is an online marketplace for premium domain names, offering more than 40,000 domains in the .ru, .su, and .рф zones. Customers can browse available names, search by keyword or other parameters, view domain details, and download the full catalogue as an Excel file. The marketplace supports both immediate online purchase and rental, with listings displaying prices and information such as domain age and search-related ratings.

Purchasing transfers the domain’s administration rights to the buyer, while rental lets customers use the domain by assigning their own DNS servers. Rental agreements include a priority right to purchase during the rental period, with the buyout price fixed in the contract; agreements can run for up to 50 months. The site also invites customers to ask questions or submit offers, and provides help, contacts, and online chat. Its catalogue includes thewallstreetjournal.ru, listed with separate purchase and monthly rental prices. SITE.su presents its services as a way for individuals and businesses to find and secure domain names suited to their needs.
