Domain Name System

How can I find out other sites registered to the same person/phone number (via whois)?

Answer 1

No way.
I personally always order a service with a domain - Hide Whois. If real Whois is required in this domain zone.
And in those domain zones where the real Whois is not required, I do not fill it out.
Not to mention the situation that some domains are not issued to me personally.
