WHOIS is a protocol used to find information about networks, ip addresses, domains and hosts. The most common use of 'whois' is for finding information about domain names (finding ownership data, registration and expiry dates, etc.) This website aims to provide more tools and information on the subject.
WHOIS is a free service provided by Link.or.id, is the most complete whois service on the internet. It automatically locates the appropriate "whois" database server for a particular domain name, queries that database for information about that domain name, and returns all available data. In addition, a domain name availability check will also be performed, even if a particular domain extension doesn't have a searchable whois database.
Tips: Before you register any domain name in the world, you must check the availablity of your desire domains by searching them with this free Whois Service. If the result is "NO MATCH" or there is no owner of it, you can register it to your favourite registrar or your favourite hosting company. You can check it twice or more if necessary or not sure!
