On the 1st January 2014 ICAAN (Internet Corporation for Assigned Names and Numbers) brought in new rules and regulations that affect gTLD (generic top-level domains) names such as .com and .net, requiring all accredited registrars and resellers to check contact information when a new domain is registered or when registrant contact information changes on existing domains.
When a new domain is registered, an email will immediately be sent to the Registrant email address specified for the domain with a link that has to be clicked in order to verify the email address. The verification email will also be sent if an edit is made to any of the following Registrant contact fields: Registrant First Name, Registrant Last name or Registrant Email Address.
The registrant will need to click on the link in the email within 15 calendar days, and once done, the contact details will be accepted as verified and will require no further verification.
If the registrant does not click on the link within 15 calendar days, then the DNS of the domain name will be taken over by the accredited registrar and a page will be posted listing instructions on how the domain can be verified and, as a result, the DNS returned to the previous settings (i.e. their site goes back online).
Once a registrant has completed the verification process, all future domain names that are updated to this same contact information will not be subject to the verification process.
