@return ClusterIPs is a list of IP addresses assigned to this service, and are usually assigned randomly.  If an address is specified manually, is in-range (as per system configuration), and is not in use, it will be allocated to the service; otherwise creation of the service will fail. This field may not be changed through updates unless the type field is also being changed to ExternalName (which requires this field to be empty) or the type field is being changed from ExternalName (in which case this field may optionally be specified, as describe above).  Valid values are &#34;None&#34;, empty string (&#34;&#34;), or a valid IP address.  Setting this to &#34;None&#34; makes a &#34;headless service&#34; (no virtual IP), which is useful when direct endpoint connections are preferred and proxying is not required.  Only applies to types ClusterIP, NodePort, and LoadBalancer. If this field is specified when creating a Service of type ExternalName, creation will fail. This field will be wiped when updating a Service to type ExternalName.  If this field is not specified, it will be initialized from the clusterIP field.  If this field is specified, clients must ensure that clusterIPs[0] and clusterIP have the same value.

This field may hold a maximum of two entries (dual-stack IPs, in either order). These IPs must correspond to the values of the ipFamilies field. Both clusterIPs and ipFamilies are governed by the ipFamilyPolicy field. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies
