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 enables individuals and businesses to buy a domain outright or rent one, with online transactions designed for immediate completion. A purchase transfers domain administration rights, while rental allows the customer to set the domain’s name-server addresses. Rental agreements include a priority right to buy the domain during the rental term, with the purchase price fixed in the agreement; contracts can last up to 50 months.

Customers can browse the full domain list, download domain data, or use an advanced search to find names by keywords and other parameters. The marketplace also provides domain-specific details, including purchase and monthly rental prices, age, and SEO-related indicators. For those interested in a particular name, such as kollekcija.ru, the site offers a way to ask a question or propose a price. Help, contact information, and online chat are available through the site’s support section.
