Why is it obligatory to enter data in the Whois? how can I change it?
The data related to the assignee or administrator of a domain name must be inserted into a public database (the Whois) managed by the competent Authority for every TLD. At the moment of registration order, the client undertakes responsibility to the communicated data. To request change of your domain’s assignee data, consult the faq regarding the assignee’s data updating operation.
