DNS, 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, 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.

Domain Name Server (DNS) used for name resolving to any hosts. Master DNS servers ( Primary Server) are the original zone data handlers and Slave DNS server ( Secondary Server) are just a backup servers which is used to copy the same zone information’s from the master servers. Master Server will resolve the names for every hosts which we defined in the zone database and use UDP protocol, because UDP protocols never use the acknowledgement process while tcp uses acknowledgement. DNS servers also use UDP protocols to resolve the query request at the earliest. Setup Master Slave DNS in RHEL/CentOS 6.5 How DNS Works? Understanding DNS might be little confusing for newbies.
