What is WHOIS (Domain Name Lookup)?

WHOIS is a database that consists of mandatory information about a registered domain, or more precisely, the registered users of an Internet resource. A WHOIS information lookup is how we can find a wider range of information on a domain name, an IP address block and the domain availability status. This includes the contact information of the registrant, mailing address, phone number, email address, domain created date, updated date, expiration date as well as the nameservers the domain is using and much more.

What is WHOIS Privacy Protection?

It is also called domain privacy. We know how damaging data breaches can be in this century, therefore, businesses take domain privacy protection seriously. WHOIS privacy protection is a service to protect domain registries/' personal information from being searched in the WHOIS records. Under the WHOIS privacy protection, some domain registries allow domain owners to hide certain details in their public WHOIS records. The contact information in a WHOIS record can be hidden from the rest of the world using a "private registration" service offered by some registrars.
