SITE.su is an online marketplace for premium domain names, offering a catalog of more than 39,000 domains, primarily in the .ru, .su, and .рф zones. The service helps businesses and individuals find a suitable name for a website, brand, or online project, with search tools for matching domains and browsing the full inventory.

Customers can purchase domains online, with administration rights transferred upon completion, or rent them on a monthly basis. Rental is arranged by assigning the customer’s DNS servers, and the agreement provides a priority right to buy the domain during the rental period, with the purchase price fixed in the contract. Rental agreements can last up to 50 months. The marketplace also lets visitors view domain details, submit questions or price offers, and download the complete catalog as an Excel file. Help, contact information, and online chat are available through the site. SITE.su focuses on making domain acquisition and rental straightforward, providing options for customers who want to secure a name immediately or use it before deciding whether to buy.
