The ownership information for domain registrations is publicly available through a service called WHOIS. WHOIS provides details about the domain name, including the registrant's name, contact information, and the domain's registration and expiration dates. It's important to note that the ownership details can vary depending on the domain extension (e.g., .com, .org, .net).


As of my knowledge cutoff date in January 2022, the Internet Corporation for Assigned Names and Numbers (ICANN) oversees the coordination of the global internet's systems of unique identifiers, including domain names. ICANN doesn't directly register domain names but accredits domain registrars, which are companies authorized to sell domain registrations to the public.


Individuals and organizations can register domain names through accredited domain registrars. These registrars, in turn, communicate with the domain registry for the specific top-level domain (TLD) to complete the registration process.


To find information about the owner of a domain, you can use a WHOIS lookup tool provided by various domain registrars or third-party services. Keep in mind that some domain owners choose to use privacy protection services offered by registrars, which replace their personal contact information with generic details to protect their privacy.
