  • network_name: String , Name of network this subnet belongs to
  • type: String , type of subnet, allowed values are “server”, “cloud” or “vswitch”
  • network_zone: String , zone of the network, see hetzner docs for ref
  • ip_range: String , ip range in IP/MASK format, must be a subnet of “network” ip_range
