Creating a Virtual Network (IPv4)

🎯 Objective

Create a Virtual Network (VNet) in Azure using an IPv4 address space to allow secure communication between Azure resources such as Virtual Machines, databases, and services.

🌐 What is a Virtual Network (VNet)?

A Virtual Network (VNet) is a logically isolated network in Azure that enables Azure resources to communicate with each other securely.

It is similar to a traditional network in a data center, but hosted in the Azure cloud.

📌 IPv4 Address Space

When creating a VNet, you must define an IPv4 address range called the Address Space.

Example

10.0.0.0/16

Explanation

This address range will be used to create subnets inside the VNet.

📊 Example Network Layout

Subnets divide the VNet into smaller networks for better organization and security.

🛠️ Steps to Create VNet (Azure Portal)

1. Sign in to Azure

1. Navigate to Virtual Network

1. Basic configuration

1. Configure IPv4 address space

1. Create a subnet

1. Review and create

🔍 Verify the VNet

Navigate to:

Virtual Networks → devops-vnet
