Name Servers
Nameservers, special computers accessible on the Internet, tell where a website is located. Nameservers are responsible for resolving, a special process in which a domain name matching your website is taken and a physical address is obtained.
The resolving process begins when a visitor goes to your website. The visitor enters your domain name in the Internet browser.The browser then searches the nameservers about the location of the server to find out just where your website is located. Then, it connects to the server and opens your web page. The whole process is similar to looking through a phone book. For example, when you pick up the phone book to look for the name John Doe, it is like the beginning of the resolving process – just like typing a name into the Internet browser. When you find the phone number, you have resolved the process; just like a nameserver helps find a website address!
While the resolving process is not something you as the website developer must complete or even need to understand, you do need to know some of the information. You will need to provide the names of the nameservers when you buy or set up your domain name. Your web host will assign your nameservers when you enroll in their hosting service. Other than that, let the computer and name server handle the rest. All you have to do is get your web page designed and on the World Wide Web.
In computing, a name server (also spelled nameserver) is a program or computer server that implements a name-service protocol. It maps a human-recognizable identifier to a system-internal, often numeric, identification or addressing component.
The most prominent types of name servers in operation today are the name servers of the Domain Name System (DNS), one of the two principal name spaces of the Internet. The most important function of these DNS servers is the translation (resolution) of humanly memorable domain names and hostnames into the corresponding numeric Internet Protocol (IP) addresses, the second principal Internet name space which is used to identify and locate computer systems and resources on the Internet.
An authoritative name server is a name server that gives answers in response to questions asked about names in zones. An authoritative-only name server only returns answers to queries about domain names that have been specifically configured by the administrator. Name servers can also be configured to give authoritative answers to queries in some zones, while acting as a caching name server for all other zones.
