SITE.su is an online marketplace specializing in premium domain names for businesses, projects, and individuals. Its catalogue features more than 40,000 domains, including keyword-based names and website addresses in the .ru, .su, and .рф zones. Visitors can browse listings, search by one or more terms, use advanced search filters, or download the full domain list for review.

The marketplace offers two ways to obtain a domain: purchase or rental. Purchases can be completed online, with domain administration rights transferred immediately. Rental is arranged by assigning the customer’s DNS servers, and selected listings include a guaranteed right to buy the domain later. Prices and rental fees are displayed alongside listing details, which may include domain age and other available indicators.

Customers can add a domain to a purchase or rental basket, submit a question, or propose a price through the site. SITE.su also provides a help section, contact information, and online chat to support visitors as they explore available names and choose an option suited to their needs.
