This service allows you to display the holder of a domain name for more than 300 domain extensions (list below). You can search an IP, a domain name accented or written in another alphabet than Latin (Arabic, Farsi, Chinese, Cyrillic, Greek, Korean...) and also a domain name written. The whois servers used are regularly updated from the list: http://www.iana.org/domains/root/db. You can therefore easily know to whom a domain name belongs.
