Whois Services

Whois Service (KRNIC's Internet Directory) provides a way of finding e-mail addresses, postal addresses who have registered "objects" with the KRNIC. Using Whois, you can also determine whether the domain name you desire is already in use; you can learn who administers a particular site; and you can view a list of site's name servers. Whois involves an online database populated with information about networks, networking organizations, domains, sites, and the contacts associated with them. This database is known as the KRNIC database. The names of the administrative And technical contacts for registered domains are automatically entered into the database when domain or IP number applications are processed by the KRNIC.

Caution : KRNIC currently provides rwhois service not whois service. But, KRNIC uses port 43. Therefore, methods of using rwhois are the same as methods of using whois. How to Use Users can query a Whois server to access this information through a local Whois client or rwhois client, an interactive telnet session, e-mail, or the KRNIC's Web-based form
