Explanations And Functions Of Name Server And Domain Name Server

A name server, also spelled as name server, is a computer server that contains a list of domain names and associated IP addresses that are connected to it.

This specialized server is used to undertake name service protocol. It works by eking out human-recognizable identifiers to system-internal addressing or identification makeup, which is often numerical.

In ordinary terms, when an Internet user inputs a domain name into his/her web browser, a name server implements the required name service protocol and subsequently connects the person to an IP address that matches with the domain name. This process cannot work, if the name server is disconnected to the Internet; so, it has to always be connected.

The most notable forms of name servers on the Internet are the domain name servers (DNS). These domain name servers translate or rather resolve human-memorable domain names and host names into matching numerical Internet Protocol (IP) addresses. An IP address is a principal Internet name space primarily used for identifying and locating computers and other resources on the World Wide Web.

Domain Name Systems:

DNS (Domain name system) is a naming system hierarchically built on a distributed database for services, computer systems or resources connected to the Internet or Intranet (private network). The most prominent function of a domain name server is the translation of domain names memorable to humans into numerical identifiers that associate with networking tools for finding and addressing these devices globally. DNS can be rightly called a sort of Internet phonebook that translates human-friendly computer hostnames into Internet Protocol (IP) addresses. A good example is that the domain name, http://bbcwebhosting.com/, resolves to the following IP address: 50.22.65.218.

The DNS enables us to allocate domain names to groups of users and Internet resources in a way that is meaningful, independent of one’s physical placement. This helps to maintain consistency and constancy of Internet contact information and World Wide Web hyperlinks, even when a participating member makes use of a mobile computing gadget or there’s a change of the present Internet routing arrangements.

Naturally humans remember domain names like bbcwebhosting.com easier than they do IP addresses, such as 50.22.65.218. This is evidently taken advantage of when Internet users recite email addresses and URLs (Uniform Resource Locators), even though a greater percentage of people don’t have a clue how computer systems effectively work to find them.

The DNS assigns domain names and name mapping to IP addresses by specifying authoritative name servers for every domain. Authoritative name servers are allocated to specific domains, and can subsequently allot other authoritative name servers for their sub-domains. This sequence of steps has helped to make DNS fault-tolerant and distributed, as well as eliminate the need for continually consulting and updating a single central register.

The DNS system is used also to store other forms of data, like a list of mail servers that receive emails for a particular Internet domain. By efficiently providing globally-distributed keyword-based redirection service, the DNS is a completely hidden part of the Internet, but incredibly important.

Domain name system can be used by other identifiers, such as international characters in hostnames and email addresses, UPC codes and RFID tags, amongst others.
