Inside a VNet, subnets allow you to segment your IP address ranges in which to place your resources. Resources in a single subnet get an IP address from the subnet IP address range. Resources in subnets within the same VNet can talk to each other. A VNet can have one or more subnets. Traffic can be filtered between subnets via either Network Security Groups (NSGs) or UDRs. It is also important to know that Azure reserves five IP addresses within each subnet that cannot be used. The reason for this is that these IPs are reserved for the network address, the Azure default gateway, Azure DNS, and the network broadcast address. An example of this is the following.

  • 10.1.1.0: This is reserved for the network address
  • 10.1.1.1: This is reserved for the default gateway
  • 10.1.1.2 and 10.1.1.3: These are reserved by Azure to map DNS IPs to the VNet space
  • 10.1.1.255: This is reserved...
