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 a domain online or rent it, including rental arrangements with a guaranteed right to buy. Purchases are completed online with immediate domain transfer, while rental involves assigning the customer’s DNS servers.

Visitors can search by one or several keywords, explore domains related by meaning or translation, use advanced search filters, or browse and download the full inventory as an Excel file. Listings show purchase and monthly rental prices, and some include details such as domain age and ratings. Customers can make an offer or ask questions about a specific domain through the site’s help section, which also provides contact information and an online chat. A shopping-cart process supports both buying and renting, while account access is available for registered users. SITE.su presents its catalog as a practical resource for businesses and individuals seeking a distinctive web address for an online project.
