Before we discuss how to install whois on ubuntu 22.04, let's first understand-What is WHOIS?

WHOIS is a command-line utility that enables users to retrieve domain registration information for a specific domain name. It is a valuable tool for querying domain details, such as the registrar, registration date, expiration date, and more.

The installation of WHOIS on Ubuntu 22.04 will be covered in this tutorial.


  1. Domain Information: WHOIS provides detailed registration information about a domain, including the registrant's contact details, registration dates, name servers, and more.
  2. Investigation and Research: WHOIS allows users to investigate the ownership and history of a domain, which can be helpful in identifying potential issues, verifying legitimacy, or resolving disputes.
  3. Monitoring Expiry Dates: WHOIS helps track domain expiry dates, ensuring that domain owners can renew their domains in a timely manner and avoid accidental loss of ownership.
  4. Security and Privacy: WHOIS assists in identifying potential domain-related security threats, such as malicious websites or spam domains, enabling users to take appropriate actions.
  5. Domain Transfer and Acquisition: WHOIS information can aid in the process of transferring or acquiring a domain by providing ownership and contact details necessary for negotiation or communication.
