If you are looking for a domain, WhoIs domain lookup can tell you if it's already owned by another entity and provide contact information for the domain name owner. WhoIs domain information can help you determine the proper contact for any domain listed in the Whois database. A WhoIs lookup identifies the administrator contact information, billing contact and the technical contact for each domain name listing or IP in the WhoIs database. A WhoIs IP search can also help you potentially determine the source of spam and other details related to a website.
The WHOIS domain database is a listing of all registered domains, and is regularly used for various legal purposes. Network administrators use WHOIS data to identify and fix problems. For instance, WHOIS information can be used to determine the availability of domain names, identify trademark infringement, and keep domain name registrants accountable.

WHOIS verification can even be utilized to combat spam or fraud, as administrators can track down registrants who post illegal content or participate in phishing scams. In addition, the agreements from The International Corporation for Assigned Names and Numbers (ICANN) protects domain registrants by prohibiting the use of WHOIS listings for marketing or spam purposes, including high-volume, automated queries against a specific registrar or registry system (unless such queries are done with the intent to manage domain names). For more information on this, read our helpful guide to navigating WHOIS.
