🌎Ever wondered how typing examplel.]com into your browser magically loads the website?💡

The answer is DNS (Domain Name System) - a crucial technology that translates human-readable domain names into IP addresses so computers can communicate. ✅

How It Works

❓

🌀 User enters a URL - The browser checks its local cache for
the IP address.

🌀 ISP's DNS cache check - If found, it's returned instantly.

🌀 Root Name Server Query - If not cached, the ISP queries a
root server.

🌀 TLD Name Server Query - Identifies the relevant name
server (.com, net, etc.).

🌀 Authoritative Name Server - Retrieves the exact IP address
for the domain.

🌀 IP address returned - The ISP's DNS caches it for future use.

🌀 Browser connects to the website using the obtained IP.

Why is DNS Important?🤔

🟢Boosts internet efficiency - Quick access to websites.
🟢Enhances security - DNS filtering helps block malicious sites.
🟢Improves redundancy - DNS caching speeds up browsing.
