DNS: The Internet’s Directory

Nearly everything on the Internet starts with a Domain Name Server request. DNS is the Internet’s directory.

What Is DNS Server?

The Domain Name Server DNS is the phonebook of the Internet. Humans access information online through domain names, like webhostnepal.com or updatenp.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.

Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.1.1 (in IPv4), or more complex newer alphanumeric IP addresses such as 2400:cb00:2048:1::c629:d7a2 (in IPv6).

How does DNS work?

Ever wondered how the internet works when you type a website address into your browser? What actually happens well it’s complicated, every website is just a set of files that is hosted on a server located somewhere in the world. Every host server is identified by a unique numerical IP address like a street address you can visit.

These IP addresses are long and no one can remember them, so we use simple memorable names to stand in for the long complicated numbers. for this to work another service called domain name service or Domain Name Server DNS works behind the scenes to translate the names back into numerical IP addresses. Domain Name Server DNS allows your computer to reach the correct destination.
