SITE.su is an online marketplace specializing in premium domain names, offering more than 40,000 domains, including keyword-focused names in the .ru, .su, and .рф zones. Customers can browse available names, search by keyword or other criteria, view domain details, and download a complete inventory in Excel. The service supports both immediate purchase and rental, with online transactions designed to make acquiring a domain straightforward.

Purchasing transfers the domain’s administrative rights to the buyer. Rental allows customers to use a domain by setting their own DNS servers and includes a contractual priority right to buy it during the rental term; the purchase price is fixed in the agreement. Rentals are priced by calendar month and may run for up to 50 months. Customers can also ask questions about a domain or propose a price through the site, with help and online chat available in the support section. SITE.su presents information such as domain age and SEO-related ratings to help visitors compare listings and choose a name for their online project.
