Whois, or how to find contacts who purchases a domain name like bernardtapie.com
When you buy a domain name, you fill the contact fields: first name, name, email address, phone. By default these fields are accessible to all, and there are very few buyers who believe in making their data inaccessible. To search the database, you use what is called whois.
Official websites like internic.net or afnic.fr do not give useful results. The one I recommend is who.is. Apart from advertisements and other video without interest, it compiles all of the most interesting data.
During your research first – on bernardtapie.com in this case – you will not find nothing very interesting: as the official engines who.is gives little information on the first page. But clicking on the small “History” tab you will find recent changes owners.
