SITE.su is an online marketplace for premium domain names, offering a catalogue of more than 40,000 domains, primarily in the .ru, .su and .рф zones. Customers can browse keyword-focused web addresses, review listed prices and compare available options for businesses, websites and other online projects.

The marketplace supports both immediate purchase and rental. Purchases are completed online, with the domain transferred promptly, while rental is arranged by pointing the customer’s DNS servers to the selected domain. Some rental offers include a guaranteed right to buy later. Visitors can search by words or topics, use advanced search parameters, view the full domain catalogue or download a spreadsheet of listings. Domain pages may also show details such as age and search-related ratings.

For customers considering a particular name, SITE.su provides a way to ask questions or submit a price offer through its contact form. Help and online chat are available in the site’s Help section, and registered users can sign in to manage their activity.
