Whois is an integral part of an information service in domain system, which is a search engine that connects the database and regulated by Network Information Center(NIC). ICANN establishes a policy that requires all of their registrars must contact each customer to verify the accuracy of their Whois information. As we all know, when a domain name is registered, Whois information is initially provided. Meanwhile, ICANN requires domain registrants keep updating their contact details a period of time. If the Whois information is correct, you do not need to take any action. On the contrary, if overdue or everythings change, even if a small thing, the information gets out of date instantly. Then you must view the Whois information for the domain names registered through Network Solutions and make change via the registrar\'s website, or call customer service.
