Where is domain name WHOIS lookup used?
A whois domain name lookup is usually done in order to find out the contact details or name of the domain name owner. In most cases, the reason for looking up the details is to get into contact with the website owner, for instance to request information or to voice a complaint. Sometimes there are legal reasons behind a domain whois lookup request.
Domain names can also be registered anonymously. This is sometimes done if the domain name owner is looking to avoid the inconveniences of spam emails or unsolicited contact requests. In such cases, the domain name is registered under the name of the domain name provider, and also the contact details of the provider are listed in the domain whois records. There are also specialized companies that offer anonymous whois services, providing the domain name owner with a privacy filter to help keep his or her identity unlisted.
