RNIDS has enabled the WHOIS service, which allows you to view the database of registered .rs domains. This service is mostly used to check whether a particular .rs domain is registered or not. If the domain is registered, the WHOIS service allows you to see information on the registrant, either a legal entity or a physical person that has registered the domain. Information RNIDS publishes within its WHOIS service is defined by General Terms and Conditions for Registration of .rs Domain Names.
This service can be used by all Internet users without any limitation and the information displayed is stored in the database of RNIDS. The WHOIS service does not show personal details of domain registrants (telephone number, e-mail address, fax number, and so on) and cannot be used in order to find out certain e-mail addresses.
Detailed information on the service is available here.
