 # Configuring private Services
 
-By default, Services deployed through Knative are published to an external IP
-address, making them public Services on a public IP address and with a public URL.
+By default, Services deployed through Knative use the `.svc.cluster.local` domain, meaning
+they are private and thus do not have a public IP address or a public URL.
 
-Knative provides two ways to enable private services which are only available
-inside the cluster:
+In order to make Knative Services public (with a public IP address and public URL) by default,
+[configure a domain name](../using-a-custom-domain.md) for the Service.
+This can be done for a single Service or for all Services on a cluster.
 
-1. To make all Knative Services private, change the default domain to
-   `svc.cluster.local` by [editing the `config-domain` ConfigMap](https://github.com/knative/serving/blob/main/config/core/configmaps/domain.yaml). This changes all Services deployed through Knative to only be published to the cluster.
-1. To make an individual Service private, the Service or Route can be
-   labelled with `networking.knative.dev/visibility=cluster-local` so that it is not published to the external gateway.
 
-## Using the cluster-local label
+## Making individual services private
 
-To configure a Knative Service so that it is only available on the cluster-local network, and not on the public internet, you can apply the
-`networking.knative.dev/visibility=cluster-local` label to a Knative Service, a route or a Kubernetes Service object.
+To make an individual Service private, the Service or Route can be labelled with
+`networking.knative.dev/visibility=cluster-local` so that it is not published to the external gateway.
