This method creates a subnetwork. To create a subnetwork, consider the following parameters:

1. Select a data center using the /v1/data-centers endpoint. The data center determines the provider and location of the subnetwork.
2. Specify the IP address range (optional). Subnetwork prefix values can have exceptions depending on that provider and must be in ranges: 10.0.0.0 - 10.255.255.255, 172.16.0.0 - 172.31.255.255, 192.168.0.0 - 192.168.255.255.

Specific conditions are depending on the provider:

• GCP: 2 first and 2 last addresses are reserved by the provider. Notice that VMs in different GCP subnetworks can be connected to each other.
• Azure: 4 first and the last ones are reserved by the provider.
• AWS: 3 first and the last one are reserved by the provider.

3. Specify the network size (required). Network size must be: for DigitalOcean /28-/16, for Gcore /24-/16, for Azure /29 - /2, for AWS /28 - /16
