What is DNS? How Does It Work?

The DNS or the Domain Name System is being used in resolving the hostnames that are readable by humans into the machine readable, which is the IP addresses. The DNS is also something that provides other information about the domain names just like the mail services. The only thing is that, why is DNS essential and how does it really work? Do everybody needs to know this thing?

Actually, the DNS is just like a phone book over the internet. If in case you know the name of the person, yet you do not know their phone number, you could just look up for it in the phone book. This works just like the same as the DNS, but the difference is that, it works on the internet. So, how does DNS works? Well, when you visit a domain, your computer will follow a series of steps that would turn up the human-readable web address into the machine-readable IP address. It actually happens each time that you are using up your domain name, whether you are viewing websites, listening to radio stations online and sending out your emails. Knowing more about the DNS and on how it really works could surely help you out.
