-If you do not control the DNS server, you can add the record to your `/etc/hosts` file. This action makes the API accessible to only you, which is not suitable for production deployment but does allow installation for development and testing.
+If you do not control the DNS server, you can access the cluster by adding the cluster domain names such as the following to your `/etc/hosts` file:
+
+* `<api_floating_ip> api.<cluster_name>.<base_domain>`
+* `<api_floating_ip> grafana-openshift-monitoring.apps.<cluster_name>.<base_domain>`
+* `<api_floating_ip> prometheus-k8s-openshift-monitoring.apps.<cluster_name>.<base_domain>`
+* `<api_floating_ip> oauth-openshift.apps.<cluster_name>.<base_domain>`
+* `<api_floating_ip> console-openshift-console.apps.<cluster_name>.<base_domain>`
+* `api_floating_ip integrated-oauth-server-openshift-authentication.apps.<cluster_name>.<base_domain>`
+
+The cluster domain names in the `/etc/hosts` file grant access to the web console and the monitoring interface of your cluster locally. You can also use the `kubectl` or `oc`. You can access the user applications by using the additional entries pointing to the <application_floating_ip>. This action makes the API and applications accessible to only you, which is not suitable for production deployment, but does allow installation for development and testing.
