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 listings, search by keyword or other criteria, view a full domain catalogue, or download a list for review. The marketplace supports both immediate purchase and rental, with online transactions designed to make acquiring a domain straightforward.

Purchasing transfers the domain’s administrative rights to the buyer. Rental gives the customer the right to change the domain’s DNS server settings and includes a contractual priority right to buy the domain during the rental term; the purchase price is fixed in the agreement. Rental is priced per calendar month, and agreements can run for up to 50 months. Visitors can submit questions or price offers through the site, with contact details required, and can access help and online chat through the Help section.

SITE.su presents domain information such as age and search-related ratings to support evaluation. Its listings include zluki.ru, available for purchase or monthly rental.
