 After you define one or more machine pools in your `install-config.yaml` file, you can define network definitions for nodes on your network. Ensure that the number of network definitions matches the number of machine pools that you configured for your cluster.

 <1> Valid network definition values include `bootstrap`, `control-plane`, and `compute`. You must list at least one `bootstrap` network definition in your `install-config.yaml` configuration file.
 <2> Lists IPv4, IPv6, or both IP addresses that the installation program passes to the network interface. The machine API controller assigns all configured IP addresses to the default network interface.
