 ## Default BrokerListener
 
-When you deploy Azure IoT Operations, the deployment also creates a BrokerListener resource named `default`. This listener is used to for encrypted internal communication between Azure IoT Operations components. The default listener is part of the [default Broker](./overview-broker.md#default-broker-resource), exposes a [ClusterIp service](https://kubernetes.io/docs/concepts/services-networking/service/#type-clusterip) on port 18883, uses [Kubernetes service account authentication](./howto-configure-authentication.md#default-brokerauthentication-resource), has an [automatically managed](#configure-tls-with-automatic-certificate-management) TLS certificate, and doesn't use any authorization.

If you need to use the ClusterIp service, add more ports to the default listener without changing any of the existing settings.
