The extranet option allows the end user to access and, when permitted, modify his data at the registry level. It can also be used by the registrant to approve his trade or transfer. If needed, the end user can be given access to the extranet to switch on some levels of control. As a first level, the registrant can ask to be informed of any change of data made by the registrar. Similarly, the registrant can choose to be informed by e-mail when his domain name is scheduled for deletion. If the end user chooses the second level of security, the modification or deletion can only be executed after confirmation from the registrant.
