SITE.su is an online marketplace specializing in premium domain names. Its catalog includes around 40,000 domains, with names available in the .ru, .su, and .рф zones. Customers can browse the full inventory, search by keywords or other parameters, and download a complete domain list for review.

The service offers both online purchase and rental. Purchases are completed with the domain’s administrative rights transferred to the buyer, while rental gives the customer the right to assign their own DNS servers. Rental agreements include priority rights to buy the domain during the rental period, with the purchase price fixed in the contract. Agreements can run for up to 50 months. The site displays information such as asking prices, domain age, and search-related indicators to help customers compare options.

For selected domains, buyers and renters can act immediately through the online cart or contact the marketplace to ask a question or propose a price. SITE.su also provides help, contact details, and online chat for customer assistance.
