Вот тот же самый сервис у namecheap.
When you register a domain, ICANN requires registrars to provide them with your contact information (such as name, email, address, and phone number). This is then added to the Whois database. This database lists the owners of every domain name online, and it can be searched by anyone on the Internet.
WhoisGuard hides this information from spammers, marketing firms, and online fraudsters. Instead, the Whois database will display generic WhoisGuard contact information.
