What is the purpose of this website?
You can do a Whois domain lookup to see who owns a domain and how long they've had it. All domain name registries keep track of information about every domain name purchased through them, including who owns it and when it was obtained.
What information is provided by Whois search?
The Whois database provides information such as the domain name's registration date, its expiration date, ownership and contact information, the domain's nameserver information, the registrar from which the domain was purchased, and so on.
