Setting Up DNS Server On CentOS 7

DNS, stands for Domain Name System, translates hostnames or URLs into IP addresses. For example, if we type www.unixmen.com in browser, the DNS server translates the domain name into its associated ip address. Since the IP addresses are hard to remember all time, DNS servers are used to translate the hostnames like www.unixmen.com to 173.xxx.xx.xxx. So it makes easy to remember the domain names instead of its IP address.
