Reference documentation and code samples for the Compute Engine v1 API enum UsableSubnetwork.Types.StackType.
The stack type for the subnet. If set to IPV4_ONLY, new VMs in the subnet are assigned IPv4 addresses only. If set to IPV4_IPV6, new VMs in the subnet can be assigned both IPv4 and IPv6 addresses. If not specified, IPV4_ONLY is used. This field can be both set at resource creation time and updated using patch.
