You don't need to memorize every part immediately. The important thing is to understand what each component does.

🌍 What Is an IP Address?

Computers communicate using IP addresses.

An IP address identifies a device or network interface on a network.

For example:

192.168.1.10

is an example of an IPv4 address used within a private network.

A public server can also have a public IP address.

The problem is that remembering IP addresses for websites would be inconvenient.

Imagine having to remember:

142.250.x.x

instead of:

google.com

That's where DNS comes in.

📖 What Is DNS?

DNS stands for:

Domain Name System

DNS translates human-readable domain names into IP addresses that computers can use to locate services on the network.

Think of DNS like the Internet's phone book.

You know the person's name.

The phone system needs their phone number.

Similarly:

Domain name

↓

DNS

↓

IP address

For example:

example.com

↓

DNS lookup

↓

IP address

↓

Server

🔄 What Happens When You Enter a Domain?

Suppose you type:

example.com

into your browser.

A simplified version is:

1. You enter example.com

↓

1.

Browser needs the server's IP address

↓

2.

DNS lookup

↓

3.

DNS returns an IP address

↓

4.

Browser connects to the server

↓

5.

Browser sends an HTTP/HTTPS request

↓

6.

Server sends a response

↓

7.

Browser displays the website

This connects several concepts we've already learned.

🧠 Putting Everything Together

Let's combine Parts 1–7.

You type:

https://shop.example.com/products/123

Step 1

The browser receives the URL.

Step 2

The browser uses DNS to find the IP address associated with the domain.

Step 3

The browser connects to the appropriate server.

Step 4

The browser sends an HTTPS request.

Step 5

The server processes the request.

Step 6

The server sends an HTTPS response.

Step 7

The browser processes the returned resources and displays the webpage.

So:

🎯 This is the foundation of how the web works.
