 ClusterIP is a virtual IP, which will not respond to ping. Best way to test if the ClusterIP is configured correctly, is by using `curl` to access the IP and port to see if it responds.

+## Why is my Layer-4 Load Balancer in `Pending` state?
 
 The Layer-4 Load Balancer is created as `type: LoadBalancer`. In Kubernetes, this needs a cloud provider or controller that can satisfy these requests, otherwise these will be in `Pending` state forever. More information can be found on [Cloud Providers](../how-to-guides/new-user-guides/kubernetes-clusters-in-rancher-setup/set-up-cloud-providers/set-up-cloud-providers.md) or [Create External Load Balancer](https://kubernetes.io/docs/tasks/access-application-cluster/create-external-load-balancer/)

+## How can I automate task X in Rancher?
 
 The UI consists of static files, and works based on responses of the API. That means every action/task that you can execute in the UI, can be automated via the API. There are 2 ways to do this:
 
 * Visit `https://your_rancher_ip/v3` and browse the API options.
 * Capture the API calls when using the UI (Most commonly used for this is [Chrome Developer Tools](https://developers.google.com/web/tools/chrome-devtools/#network) but you can use anything you like)
 
-### The IP address of a node changed, how can I recover?
+## The IP address of a node changed, how can I recover?
 
 A node is required to have a static IP configured (or a reserved IP via DHCP). If the IP of a node has changed, you will have to remove it from the cluster and readd it. After it is removed, Rancher will update the cluster to the correct state. If the cluster is no longer in `Provisioning` state, the node is removed from the cluster.

 You can add more arguments/binds/environment variables via the [Config File](../reference-guides/cluster-configuration/rancher-server-configuration/rke1-cluster-configuration.md#rke-cluster-config-file-reference) option in Cluster Options. For more information, see the [Extra Args, Extra Binds, and Extra Environment Variables](https://rancher.com/docs/rke/latest/en/config-options/services/services-extras/) in the RKE documentation or browse the [Example Cluster.ymls](https://rancher.com/docs/rke/latest/en/example-yamls/).
