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 store lets individuals and businesses purchase domains or rent them by the month, offering an online process for immediate purchase and transfer of domain administration rights.

Rental agreements may last up to 50 months.

Customers can browse the full domain inventory, download listings, and use advanced search to find names by keyword or related terms. Listings show purchase and monthly rental prices, along with domain age and rating information. The marketplace also provides a contact form for questions or price offers, plus help and online chat. SITE.su publishes articles and domain reviews, including information about the potential value and online use of specific domain names.
