In simple terms, WHOIS is a tool that can be used to check domain availability, status and at times to know who manages a certain domain name. This is a global catalogue that provides information about existing domain names* and all relevant information. Information records within WHOIS may vary, but in general, this record will show the domain registrant contact, registrar, nameservers, registration/ expiration dates and domain status.
* Not applicable to selected TLDs/ccTLDs due to regulatory restrictions.
Whois lookup plays an essential role in verifying the accuracy of essential details associated with a specific registered domain, thereby minimising fraudulent activities and preventing identity theft.
According to the ICANN requirement, the registrant (who owns the domain) must provide and maintain a publicly viewable database that displays the personal contact information when registering a domain, as it helps them to regulate domain registration and ownership.
However, may opt to make some data private and ensure domain name registrant information is kept hidden in the presence of domain proxy/privacy offered by sponsoring registrar.
Furthermore, some information, especially sensitive details about the registrant, is often redacted from the public listings that anyone can access when searching the WHOIS directory for confidentiality. Customer information including a registrant’s name, email country of residence, phone number and other private information are masked by the registrant contact details through activation of whois privacy/proxy service.
