DNS: The Internet Address Book
Once upon a time in a hustling, digital city called the Cyberia, there lived a web surfer named Noah. Noah loved exploring the vast world of websites, but there was one problem: the Cyberia was so enormous, it was impossible to remember the precise location of every website.
One morning, Noah decided to visit a website known as “Arima”. But how could Noah find it in the vastness of the Cyberia? That’s when a friendly guide named Dot appeared.
Dot was like a master mapmaker of the Cyberia. Dot explained, “To find ‘Arima’, you need an address just like you need one to find a house in your neighborhood. But on the internet, we call these addresses ‘Domains’.”
Noah was curious and asked, “How do I get a domain, and what’s it like?”
Dot led Noah to a place called the “Domain Registrar.” It was like a store for internet addresses. There, Noah found a catalog filled with unique domain names, like “www.arima.one”, “www.example.com”.
“You see,” Dot explained, “just like you can’t have two houses with the same street address in the real world, you can’t have two websites with the same domain name in the Cyberia.”
Noah picked “www.arima.one” from the catalog and paid for it. Now, Noah had a special address for the Arima website.
But there was one more step. Dot mentioned, “We need a way to translate this domain into the real location of the website. It’s like knowing the name of a building but not the exact coordinates.”
That’s when they visited the “DNS Office,” which was like the phonebook for the Cyberia. Noah told the friendly DNS worker, “I want to find ‘Arima’, here’s my domain ‘www.arima.one’.”
The DNS worker smiled and said, “No problem! I’ll find the building’s coordinates for you.” The DNS worker translated “www.arima.one” into the real address (the IP address) of the Arima website.
Noah’s adventure to “Arima” began. Thanks to the domain, Noah could easily find and explore the website.
But wait, Dot had more to explain! “You see, the part of the domain name that comes after the last dot, like ‘.com’, ‘.net’, ‘.org’, or ‘.one’ is called the domain name extension. It often tells you what the website is about. For example, ‘.com’ is for commercial websites, ‘.net’ is often used for networking and tech-related sites, ‘.org’ is for organizations and ‘.one’ is to represent being the top choice in their industry”.
Noah realized that the domain extension was like a little tag that provided extra information about the website. It helped Noah understand what kind of place “Arima” was even before visiting.
And from that day on, Noah understood that domains, along with their extensions, were like the street signs of the Cyberia, making it easy for everyone to navigate the vast digital city while also giving hints about the nature of the websites they led to.
