Use this function to test your CIDR Ranges

This simple function can be used to test the CIDR ranges that will be built by Terraform when using the cidrsubnets function.

Instructions to run CIDR Tester

1. Copy the cidrtest.tf into a folder with no other Terraform files.

2. Update the CIDR range of the VNET

locals {
    vnet_mgt_cidr = "192.168.0.0/20"
}

3. Save the file and run the following command in the folder

terraform apply

4. The output will show the networks you have created.

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

Outputs:

subnets = [
  {
    "cidr" = "192.168.0.0/24"
    "name" = "subnet1"
  },
  {
    "cidr" = "192.168.1.0/24"
    "name" = "subnet2"
  },
]

More CIDR ranges can be added to the array to help you tweak the values to match up to the requirements for your VNETs.
