SITE.su is an online marketplace specializing in premium domain names, with more than 40,000 domains available across the .ru, .su, and .рф zones. The service enables customers to purchase domains online or rent them, including rental arrangements with a guaranteed right to buy. Purchases are described as available instantly, with online transfer of the domain, while rental is arranged by assigning the customer’s DNS servers.

The marketplace provides tools to browse its full domain inventory, download a domain list, and search using keywords or more detailed criteria. Listings include purchase and monthly rental prices, and may show information such as domain age and search-related statistics. Customers interested in a particular name can submit a question or offer a price, and the site directs visitors to its Help section for contact details and online chat.

SITE.su presents domains for businesses, personal projects, and other online ventures. Its listing for dezhurstvo.ru, for example, offers both purchase and rental options, illustrating how customers can choose between acquiring a domain outright or using it through a monthly rental.
