Creating an Azure Virtual Network with Subnets

Creating an Azure virtual network (VNet) with four subnets using the address space 192.148.30.0/26 involves several steps in the Azure portal. Below is a step-by-step guide with screenshots to help you through the process:

Step 1: Sign in to Azure Portal

  • Open your web browser and navigate to the Azure Portal.
  • Sign in with your Azure account credentials.
    ### Step 2: Create a Resource Group (if needed)

If you do not already have a resource group where you want to create the virtual network, you can create one:

  • In the Azure portal, click on Resource groups in the left-hand menu.
  • Click + Add to create a new resource group.
  • Fill in the required details (Subscription, Resource group name, Region), and click Review + create and then Create.

Step 3: Create a Virtual Network

Now, let’s create the virtual network with the specified address space and subnets:

  • In the Azure portal, click on Virtual networks from the home page, then click + Create.

  • Subnet Address range: Specify the subnet range within the virtual network address space (192.148.30.0/26). Ensure each subnet range is within the /26 address space (192.148.30.0 to 192.148.30.63)

    • For Subnet-1: 192.148.30.0/28192.148.30.15/28
    • For Subnet-2: 192.148.30.16/28192.148.30.31/28
    • For Subnet-3: 192.148.30.32/28192.148.30.47/28
    • For Subnet-4: 192.148.30.48/28192.148.30.63/28
      • Click Add for each subnet after configuring its details.
