How to install whois on CentOS server

While moving a web site, i want to check whois of the domain to find name servers. I run

root@vps73324 [~]# whois customer-domain-name.com
-bash: whois: command not found
root@vps73324 [~]#

Whois is not installed, we need to install it.

To find which package provide whois command, run

root@vps73324 [~]# yum whatprovides "*/bin/whois"
