SITE.su is an online marketplace for premium domain names, offering more than 40,000 domains across the .ru, .su, and .рф extensions. Customers can browse names, search by keywords or other parameters, and review related information such as listed prices, domain age, and available ratings and statistics.

The marketplace offers two ways to use a domain: purchase it online with immediate transfer, or rent it by assigning the customer’s DNS servers.

Visitors can submit a question or offer a price for a specific name, while account access supports registration and sign-in. SITE.su also provides help and online chat through its Help section, along with options to view the complete domain inventory or download a list in Excel format.
