WHOIS Knowledge Base

WHOIS is a query and response protocol that queries databases containing the registered users or assignees of an Internet resource, such as a domain name, IP address block, or autonomous system. The protocol stores and delivers database content in a human-readable format. WHOIS services are typically operated by registrars and registries, providing essential information about domain ownership and administrative contacts.
