WHOIS (pronounced as the phrase "who is") is a query and response protocol that is used for querying databases that store an Internet resource's registered users or ...
[1] Domain names are managed under a hierarchy headed by the Internet Assigned Numbers Authority (IANA), which manages the top of the DNS tree by administrating the data in the root nameservers . IANA also operates the int registry for intergovernmental organizations, the arpa zone for protocol administration purposes, and other critical zones ...
In computer networks, a reverse DNS lookup or reverse DNS resolution (rDNS) is the querying technique of the Domain Name System (DNS) to determine the domain name associated with an IP address – the reverse of the usual "forward" DNS lookup of an IP address from a domain name. [1]

If the whois information had been out of date and is now updated, the end-user should wait 12–24 hours before proceeding further, to allow time for the updated data to propagate. The end user contacts the new registrar with the wish to transfer the domain name to their service, and supplies the authentication code.
RFC 2832, section 6, and RFC 3632, section 2.1, lists the different status codes and their descriptions. When a domain name is protected by REGISTRAR-LOCK at the registrar level the domain name will have the status code "ClientUpdateProhibited. [4]" The status codes of domain name can be found using the WHOIS system. [5]
In 2017, GoDaddy acquired the security platform Sucuri.

The WHOIS protocol is still widely used to allow domain ownership records in the Internet to be easily queried.
