Domain Name Server

Introduction

DNS server is a service that assist in translating the web address or the domain name into IP number. Although the web address is given alphabetically this is easier to remember however the internet is mainly based on IP number. For instance if one enters the web address as www.example.com this will be translated into IP number as 198.105.232.4. A DNS server network has been formed that enables to translate the domain name into IP number, if one server fails to translate the domain name another server is contacted for translating the domain name (Baggett, 2011).

Domain Name Server

Domain name server assist the user by making it convenient for him to remember the domain name instead of memorizing the IP number which is difficult for the user. The task of domain name server is to translate the domain name into IP number. It identifies the process of how data is exchanged on the internet. The process can better be understood with an example, that is the DNS server works similar to when an individual dials a number to reach another person, thus one has to keep a phonebook for recording these numbers, however with DNS server individuals do not have to remember numbers and it's just the domain name that has to be memorized for accessing the required website, which makes internet even more user friendly. Individuals can find IP number for their domain names (www.webopedia.com).

Primary Name Server

The primary name server is responsible to read the information related to domain zone that is received from a file which has been stored on the web server of hosting package. Primary server will then be responsible for communicating this information to secondary DNS server. This process can therefore be defined as zone transfer as it allows exchange of data between primary and secondary DNS servers. The purpose of primary of DNS server can be simply explained as when the user makes a request to the server it has to pass through primary DNS server which then allocates the data to secondary DNS server to be translated further (Baggett, 2011).

Secondary Name Server

Secondary name server can also be referred to as slave server. The task of secondary DNS server is to take data from primary DNS server once it has been set up. For every domain name there has to be two name servers that is primary and secondary. Secondary name server has the responsibility of copying information from primary server for the domain. This information is copied automatically from the primary name server by the secondary name server and hence the domain does not differentiate between the two name servers. Both the name servers are utilized equally when the user searches for any domain name. Secondary and primary name servers are equally important, secondary server also assist to mitigate the load from primary name server (www.webopedia.com).
