For more details on the different networking providers and how to configure them, please view our [RKE2 documentation](https://docs.rke2.io/install/network_options/).
##### Dual-stack Networking
[Dual-stack](https://docs.rke2.io/install/network_options/#dual-stack-configuration) networking is supported for all CNI providers. To configure RKE2 in dual-stack mode, set valid IPv4/IPv6 CIDRs for your [Cluster CIDR](#cluster-cidr) and/or [Service CIDR](#service-cidr).
###### Additional Configuration {#dual-stack-additional-config}
When using `cilium` or `multus,cilium` as your container network interface provider, ensure the **Enable IPv6 Support** option is also enabled.
#### Cloud Provider
You can configure a [Kubernetes cloud provider]({{<baseurl>}}/rancher/v2.6/en/cluster-provisioning/rke-clusters/cloud-providers). If you want to use dynamically provisioned [volumes and storage]({{<baseurl>}}/rancher/v2.6/en/cluster-admin/volumes-and-storage/) in Kubernetes, typically you must select the specific cloud provider in order to use it. For example, if you want to use Amazon EBS, you would need to select the `aws` cloud provider.

Instead of using the Rancher UI forms to choose Kubernetes options for the cluster, advanced users can create an RKE2 config file. Using a config file allows you to set any of the [options](https://docs.rke2.io/install/install_options/install_options) available in an RKE2 installation.
To edit an RKE2 config file directly from the Rancher UI, click **Edit as YAML**.
