Domain name owners know that acquiring a domain comes with extensive learning about DNS. One of the most important terms you will learn as a result of purchasing your domain will be propagation.
Valid WHOIS information is also needed to conduct a domain name transfer. Additionally, it is used by law enforcement for criminal investigations, by the public to determine when a domain has expired, by anyone who wants to contact the domain name owner. With this information, we can determine the owner of a domain name, its contact person in the event of a problem (the domain name administrative contact), and the technical contact administering the domain name.
