   The Cluster Domain field is the base DNS domain used to construct fully qualified pod and service domain names.

   The Cluster IP is the address pods query for name resolution. The IP is defined as the 10th address in the service CIDR range.

   $ oc get networks.config/cluster -o jsonpath='{$.status.serviceNetwork}'
