| = Configuring the DnsRecordsType parameter | ||
|
|
||
| [role="_abstract"] | ||
| During cluster installation, you can specify the `DnsRecordsType` parameter in the `install-config.yaml` file to set if the internal DNS service or an external source provides the necessary records for `api`, `api-int`, and `ingress` DNS records. | ||
|

||
| :FeatureName: Configuring the DnsRecordsType parameter | ||
| include::snippets/technology-preview.adoc[] | ||
|
|
||
| The `dnsRecordsType` parameter supports the following values: | ||
|
|
||
| * `Internal`: The default value. Setting this value causes the cluster infrastructure to automatically create and maintain the necessary DNS records. | ||
| * `External`: You can use this value only if you set the `loadBalancer.type` parameter to `UserManaged`. The cluster does not manage the DNS records. You must manually configure DNS records on an external DNS server. | ||

| * You created DNS records, such as `api`, `api-int`, or `\*.apps`. | ||
| * You configured a user-managed load balancer for your cluster. | ||
| * If you intend on setting `dnsRecordsType.External` in the `infrastructure.config.openshift.io` CR , you must initially configure cluster nodes to use the specific external server for DNS resolution. | ||
