Workload Cluster Network CIDR Ranges
Review the example CIDR ranges used for OKE network resources on Compute Cloud@Customer.
Throughout this documentation, variables are used to represent CIDR ranges for instances in different subnets. The following table lists the CIDR variables and example values. Change these example values as necessary for your environment. The IP Subnet Calculator on Calculator.net is one tool for finding all available networks for a given IP address and prefix length.

Next Step:
Depending on how you want to create the network resources, see one of the following sections:
- Use Terraform scripts to automate the creation of the network resources. See Example Terraform Scripts for Network Resources.
- Begin to create the network resources using the Compute Cloud@Customer Console, CLI, or API. See Configuring OKE Network Resources Individually.
