Name Server
Name Server translates the website domain names to respective IP addresses. While registering the domain, each domain name must have at least two name servers listed. First Server is known as Primary Name Server, while Secondary Name Server is used for backup purposes (when the Primary Name Server is not responding). Name servers make it possible for the website visitors to enter domain names instead of IP addresses. Foe examples, when you enter www.intiger.com in you address bar, the request gets sent to Intiger's name server which returns the IP address of Intiger Website.
