How to use whois command in Linux
whois command in Linux-based operating systems is a utility tool to list and find the detailed domain information. This command not only identifies the domain information but also helpful in finding Unknown and distant hosts, and Net-admins if whois is used properly.
There are lots of attributes in domain names, such as:
- Name Server
- Geographical Location
- IP history
To install whois command in Ubuntu, Debian, Mint & Kali type the following command without quotes:
” sudo apt install whois ”
To install whois command in Fedora, CentOS, RHEL type the following command without quotes:
” sudo yum install whois ”
Newer versions of Kali Linux comes pre-loaded with whois client.
whois database provides us personal details. To use this command in Kali Linux the syntax is:
whois <ip address/name of the website>

The behavior of whois command is different for the site name and IP address.
When we use this command with IP Address, we get information about addresses, Net-Type, Net-Handle, Organizational details and much more.
And if we use this command with site-name, Registrar details and Registrar URL. This information is certainly less in size.
