# Zilla::IoK8sApiNetworkingV1alpha1ClusterCIDRSpec ## Properties | Name | Type | Description | Notes | | ---- | ---- | ----------- | ----- | | **ipv4** | **String** | IPv4 defines an IPv4 IP block in CIDR notation(e.g. \"10.0.0.0/8\"). At least one of IPv4 and IPv6 must be specified. This field is immutable. | [optional] | | **ipv6** | **String** | IPv6 defines an IPv6 IP block in CIDR notation(e.g. \"fd12:3456:789a:1::/64\"). At least one of IPv4 and IPv6 must be specified. This field is immutable. | [optional] | | **node_selector** | [**IoK8sApiCoreV1NodeSelector**](IoK8sApiCoreV1NodeSelector.md) | | [optional] | | **per_node_host_bits** | **Integer** | PerNodeHostBits defines the number of host bits to be configured per node. A subnet mask determines how much of the address is used for network bits and host bits. For example an IPv4 address of 192.168.0.0/24, splits the address into 24 bits for the network portion and 8 bits for the host portion. To allocate 256 IPs, set this field to 8 (a /24 mask for IPv4 or a /120 for IPv6). Minimum value is 4 (16 IPs). This field is immutable. | | ## Example ```ruby require 'zilla' instance = Zilla::IoK8sApiNetworkingV1alpha1ClusterCIDRSpec.new( ipv4: null, ipv6: null, node_selector: null, per_node_host_bits: null ) ```
