What is WHOIS?
WHOIS is a protocol that allows an individual to find the owner of a domain name and the contact information for the person who registered it.
WHOIS was created in 1985 by Jon Postel, as part of his work at the University of Southern California Information Sciences Institute. The idea behind WHOIS was to provide a central database where anyone could query for information about domain names and contact details associated with them.
WHOIS was originally developed by ARPANET and DARPA in 1979, but it wasn’t until 1985 when it became an Internet standard.
The WHOIS database is maintained by individual domain name registrars, and so it is possible for different domains with the same owner to have different WHOIS records.
WHOIS was originally developed as a way for network administrators to keep track of IP address assignments within their networks. As domains became more popular, WHOIS became a way to track who owns which domains and how they are being used.
