SITE.su is an online marketplace for premium domain names, offering customers a choice of more than 40,000 domains, primarily in the .ru, .su, and .рф zones. The service focuses on keyword-rich domains and provides two ways to obtain them: immediate online purchase with domain transfer, or rental by assigning the customer’s DNS servers. Rental options can include a guaranteed right to buy the domain later.

The marketplace lists available domains with purchase and monthly rental prices, and provides search tools to find names by keyword or other parameters. Customers can browse the full catalog online or download a complete domain list as an Excel file. Listings may also include details such as domain age and available search or rating metrics.

For customers interested in a particular name, SITE.su offers a way to ask questions or propose a price, as well as online help and chat through its Help section. The service is designed to make discovering, comparing, renting, and buying domain names straightforward.
