2. Add a New Resource Group: Click on the + Create button at the top of the Resource Groups page.
3. Fill in the Details: Subscription: Select the appropriate subscription. Resource Group Name: Enter a name for the new resource group. Region: Choose the region where you want the resource group to be located. Click Review + create, then Create to finalize the creation of the resource group.

Step 3: Create a Virtual Network
To create the Virtual Network with the specified address space and subnets, follow these steps:

1. Go to the Azure Portal Home Page: Open the Azure Portal.
2. Navigate to Virtual Networks: Click on Virtual networks from the left-hand menu.
3. Start the Virtual Network Creation Process: Click the + Create button at the top of the Virtual Networks page.

1. Subscription: Select the Azure subscription you will use for this Virtual Network.
2. Resource Group: Choose the existing resource group or create a new one for your Virtual Network.
3. Name: Enter a unique name for your Virtual Network.
4. Region: Select the Azure region where the Virtual Network will be deployed.

Enter Address Space:
Type 10.1.0.0/16 for the IPv4 address space.

Number of Addresses:
This address range provides a total of
65,536 addresses IP addresses for the Virtual Network.
The following image shows that 10.1.0.0/16 provides
65,536 addresses addresses within this network.

Below is an illustration of how the 10.1.0.0/16 address space is organized:

IP Range Total Addresses
10.1.0.0 - 10.1.0.255 65,536 addresses

Step 4: Detailed Instructions to Configure Subnets
Navigate to Subnets:
In the Virtual Network settings, find and select the Subnets tab.
Add a Subnet:
Click + Add subnet to start configuring each subnet.

Subnet Name:
Provide a unique name for the subnet, such as Subnet-1, Subnet-2, etc.
Subnet Address Range:
Define the IP range for the subnet within the 10.1.0.0/16 address space. For example, you might use 10.1.1.0 - 10.1.1.255 for one subnet and 10.1.3.0 - 10.1.3.255 for another. Ensure the ranges are within 10.1.0.0 - 10.1.0.255
Add the Subnet:
After configuring the details, click Add to create the subnet.

Step 5: Review and Create
Once you’ve added all four subnets, click Review + create to verify the configuration and click Create to deploy the Virtual Network and its subnets.

Step 6: Deployment Progress
Wait:
Allow time for Azure to complete the deployment process. This typically takes a few minutes.
Step 7: Verification

1. View the Resource:
   Click Go to resource to access the Virtual Network after deployment finishes.

2. Verify Subnets:
   Go to Settings and select Subnets to confirm that the subnets are set up correctly.
   

Congratulations!
You have successfully created an Azure Virtual Network with four subnets using the address space 10.1.0.0/16.
Alternative Clear and Precise Versions.

By completing these steps, you will set up the basic configuration for your Virtual Network.
