SITE.su is an online marketplace for premium domain names, offering more than 40,000 domains across the .ru, .su, and .рф zones. Customers can browse, search by keywords or other criteria, view domain information, and download a complete listing in Excel. The marketplace supports both immediate purchase and rental, giving businesses and individuals flexible ways to secure a suitable web address.

Purchasing a domain transfers its administrative rights to the buyer through an online process. Renting allows customers to assign their own DNS servers, with the fee charged monthly. Rental agreements include a priority right to purchase the domain during the contract, with the buyout price fixed in advance; agreements can last up to 50 months. Listings may include details such as domain age and a rating based on search-related indicators.

SITE.su also provides an inquiry and negotiation option for customers who wish to ask about a domain or propose a price. Help resources, contact information, and online chat are available through the site’s Help section.
