Nameservers can be described as special computers that can be accessed on the Internet and that inform the location of a website. Nameservers basically undergo the resolving process wherein a domain name that matches your website is retrieved and a physical address thereof is attained. This process commences soon after a visitors enters your website and when he enters your domain name in the Internet browser. Then the browser looks for the Nameservers for the location of the server to find out where exactly is your website located.
It then connects to the server to open your web page. While this entire process is not your baby to take care of, you must certainly keep yourself abreast with the relevant information.
Soon after you buy your domain name and set it up, you have to provide the names of the nameservers. After you enrol into the hosting service with your web host, they will assign your nameservers. Only this much is what is required on your part and the rest will be taken care of by the nameserver. Just get your web page designed properly and you can relax!
A Nameserver is said to possess details regarding the naming scheme to the IP addresses for a website. After you register your domain name, a Nameserver configures a ‘Zone’ for your domain connecting it to an IP address, also known as a “Record’. There is an ‘MX Record’ too that exemplifies a zone again on a Name Server which is used for identifying the mail server. For instance, when anyone emails you, their mail server sends a request to the Nameserver for your domain to obtain its IP address, before the email is sent to the mail server.
At the same time, a Domain Nameserver can only store domain names and the IP addresses associated with them, for a specified period of time in a cache. If a request is made for an IP address and the DNS server is not having the same address in its cache, the latter will make a request to a set of special servers holding the addresses for all nameservers. Then the DNS requests the IP address for the domain name from the nameserver. The DNS is completed with the original request once the information is attained.
