I want you to imagine something. I want you to consider how many websites exist in the world today. There have to be thousands, right? Noooo, way more than that! Millions! Millions of different websites that can be accessed today. Now, think about how you access them. You don’t type a whole bunch of random numbers into your computer and hope that the right website comes up. That is ludicrous! And I know that we certainly are not capable of storing millions of different IP addresses in our minds, being able to access the ones that we need at will. That, again, is ludicrous. So how, then, are we able to access the various results of web hosting world wide? The answer is simple: DNS.
Web hosting, and in particular dns hosting, is very essential for the existence of the internet. Without DNS hosting, the internet could exist, but it would be almost unnavigable. Essentially DNS stands for Domain Name Servers, and they are what allow you to access the web sites that you need. DNS servers were in a hierarchical manner, with 13 main servers existing worldwide that contain every single website in the world. Servers below these don’t contain as many names, and the lower down the hierarchy, the less names the server will know.
So how do they work? Well, imagine that your website is located on some specific dedicated servers. It has an IP address, an allocation of seemingly random numbers that humans don’t really tend to understand well. So how do people find your website? Well, located on a DNS server somewhere will be the name of your website, and right beside it, the IP address that corresponds to it. Suddenly your dedicated servers went from being nameless numbers to something that we can understand! This is what DNS is!
Essentially, without DNS, people would never find your website. It’s like if you’re learning a new language. You don’t know what certain words mean, but you need to find out, because they are very important for you. So what do you do? Well, any sane man would consult a dictionary, first of all (or in this day jump on Google translate). This is the exact same thing as your web browser querying a DNS server, asking it what this name means, in the language that it speaks, which being a computer is numbers! So essentially DNS servers are huge dictionaries that allow your computers and the millions of other computers in the world to find your website, and without these DNS servers, your website would be almost useless. You can see how important they are!
All in all, DNS servers do more than just take extra bandwidth and space. They allow the internet to be what it is today. They allow it to be fast and efficient and organized, and if DNS servers didn’t exist, the internet would be almost unusable! As such, be sure to make sure that your website is registered in the DNS server of your internet provider, or you’ll never get any visitors.
