“Here’s a short, simple, and copyright-free version you can post directly on your blog:
🌐 What is DNS?
DNS stands for Domain Name System.
It’s like the phonebook of the internet.
- Humans use names (like
www.google.com). - Computers use numbers (IP addresses, like
142.250.72.196). - DNS is the system that translates names into numbers so browsers and apps know where to connect.
🔹 Example
When you type facebook.com in your browser:
- Your computer asks a DNS server: “What’s the IP address of facebook.com?”
- DNS replies with the correct IP.
- Your browser connects to that IP → website loads.
🔹 Why It Matters
- Without DNS, you’d have to remember long IP addresses.
- With DNS, the internet becomes human-friendly and easy to use.
