Whois

Whenever a domain is registered, the International Corporation for Assigned Names and Numbers (ICANN) requires that these individuals, businesses or organizations provide up-to-date personal contact information to their domain registrars. This information, which may include the name, address, email, phone number and associated IP addresses, is collected and displayed in the ICANN WHOIS Database, which acts similarly to an international address book for the public.

Utiliti uses Cloudflare's Whois API to return information about the domain name.
