concepts

• For dealing with ip address related stuff terraform has ip functions and we have used cidrsubnet function to calculate subnet cidr based on network range Refer Here
• For generating graph or understading the order of creation we can use terraform graph command which generates graph in dot format Refer Here and graph can be visualized Refer Here
• Variable type map or object Refer Here
