Microsoft Azure (AZ-104): Understand Virtual Networks

  • The first and last IP in each subnet is reserved for the network identification and for broadcast, respectively.
  • Azure also holds 3 additional addresses for internal use starting from the first address in the subnet.
  1. To ensure your Azure web app connects to SMB share on your on-premises network, you need a VPN gateway. Don’t confuse it with Azure Application Gateway. Azure Application Gateway is a web traffic load balancer. It does not provide connectivity to on-premises resources.
  2. You can’t add address ranges to, or delete address ranges from a virtual network’s address space once a virtual network is peered with another virtual network. To add or remove address ranges, delete the peering, add or remove the address ranges, then re-create the peering.
