SITE.su is an online marketplace for premium domain names, offering a large selection of domains in the .ru, .su and .рф zones. The service is designed for individuals and businesses seeking a web address for a new project or an existing website. Customers can browse the full domain catalogue, search by words or other criteria, and download a list of available domains in Excel format.

Domains can be purchased online, with administration rights transferred after purchase, or rented by the month. Rental includes the right to change the domain’s name server settings and a contractual priority option to buy the domain during the rental period; the purchase price is fixed in the agreement. The marketplace also provides an enquiry form for questions or price offers, along with help information and online chat access.

Listings display purchase and monthly rental prices, and may include details such as domain age and search-related indicators. SITE.su presents these options to help customers compare names and choose an arrangement suited to their project and budget.
