Objective

Design and deploy an Azure Virtual Network with subnets.

Tools & Technologies

  • Azure VNet
  • Azure CLI
  • subnets

Key Commands

az network vnet create --name MyVNet --address-prefix 10.0.0.0/16
az network vnet subnet create --name WebSubnet --address-prefix 10.0.1.0/24
az network vnet peering create

Lab Steps

01
VNet Creation

Create a VNet with custom address space using Azure CLI.

02
Subnet Design

Design and create subnets for different tiers (web, app, db).

03
VNet Peering

Configure peering between two VNets in the same region.

04
DNS Settings

Configure custom DNS servers for the VNet.

Challenges Encountered

  • Overlapping address spaces break VNet peering
  • Subnets cannot overlap within a VNet

Key Takeaways

  • Plan address space before deployment — cannot be changed easily after
  • Use /24 subnets unless you specifically need smaller or larger
