DNS is the Domain Name System, which maintains a database that can help your computer
translate domain names such as www.redhat.com to IP addresses such as 126.96.36.199. As
no individual DNS server is large enough to keep a database for the entire Internet, they can refer
requests to other DNS servers.
DNS is based on the named daemon, which is built on the BIND (Berkeley Internet Name Domain)
package developed through the Internet Software Consortium
Users wants to access by name so DNS will interpret the name into ip address. You need to
specify the Address if DNS server in each and every client machine. In Redhat Enterprise Linux,
you need to specify the DNS server into /etc/resolv.conf file.
After Specifying the DNS server address, you can verify using host, dig and nslookup commands.
