What is Domain Name Server?

Learn about Domain Name Server:

Every computer is assigned a unique address called IP address, which enables other users in identifying it using Internet Protocol. A typical IP address looks like this “199.164.386.5”.  In a layman’s term, a Domain Name Server (DNS) is the internet’s phonebook. DNS acts as a directory of domain names and their matching IP addresses. This directory assists other computers in knowing where they need to go to search your website.

For any human being, it is quite impossible to remember the IP addresses of all the websites we use on a daily basis. But, when it comes to memorizing words it is possible to remember it. This is where DNS comes into play. When visiting a website all we need to remember is its URL. Computers being machines can easily remember and store numbers and DNS helps us in converting the URL into an IP address which is understandable by the computers.

For example, when we type abc.com in our browser, the browser first needs to fetch the IP address of www.abc.com. Then the browser connects to a DNS server to inquire about the location of the server where the webpages of abc.com are stored.

Like to find out the contact details of any mall, store or any other thing we search through the pages of the phonebook directory like “The Yellow Pages”. Once we find the contact details then either we call them or visit them personally to get our work done. Similar is the process of the DNS server.
