DNS Domain Name System

The DNS or also known as Domain Name System is responsible for associating names like www.google.com with their corresponding IP addresses. The computer uses the DNS to look up domain names and get the IP address, which is then used to connect it to its destination on the internet. One main DNS server is not enough, so they are connected in a distributed hierarchy divided into zones. The zones are split up and overlook major domains like .com, .org, and .net. Since the DNS was originally made to be an open public communication procotol, it is prone to cyber attacks, like spoofing.

Why do we use the Domain Name System?

Google.com. Yahoo.com. Youtube.com. These are just a few of the well known websites, which have their own IP addresses that most Internet users never notice or disregard. Luckily, the DNS connects the domain names with the address. Without the DNS, users would have to memorize each unique IP addresses for each domain.
