# Step 8: Create a Custom DNS Name (Optional)

{% hint style="info" %}
After you create a Load Balancer Listener you can modify the DNS Name for ease of use and reference by your applications. It isn't necessary to run your application or complete this tutorial.

To skip this step, proceed to [test your application and complete this tutorial](/docs/automation-platform/overview/quick-start/quick-start-eks-services/step-9-test-the-application.md).
{% endhint %}

Once the Load Balancer is created, DuploCloud programs an autogenerated DNS Name registered to **demo-service** in the [Route 53](/docs/automation-platform/overview/prerequisites/route-53-hosted-zone.md) domain. Before you create *production* deployments, you must [create the Route 53](/docs/automation-platform/overview/prerequisites/route-53-hosted-zone.md) Hosted Zone domain (if DuploCloud has not already created one for you). For this tutorial, it is not necessary to create a domain.

*Estimated time to complete Step 8: 5 minutes.*

## Prerequisites

Before securing a Load Balancer, verify that you completed the tasks in the previous tutorial steps. Using the DuploCloud Portal, confirm that:

* An [Infrastructure and Plan](/docs/automation-platform/overview/quick-start/step-1-infrastructure.md) exist, both named **NONPROD**.
* The **NONPROD** infrastructure has [EKS **Enabled**](/docs/automation-platform/overview/quick-start/step-1-infrastructure.md#check-your-work).
* A Tenant named [**dev01** has been created](/docs/automation-platform/overview/quick-start/step-2-tenant.md).
* A Host named [**host01** has been created](/docs/automation-platform/overview/quick-start/quick-start-eks-services/step-3-create-host.md).
* A Service named [**demo-service** has been created](/docs/automation-platform/overview/quick-start/quick-start-eks-services/step-5-create-app-via-k8s.md).
* An [HTTPS ALB Load Balancer](/docs/automation-platform/overview/quick-start/quick-start-duplocloud-docker-services/step-6-create-loadbalancer.md) has been created.

## Creating a Custom DNS Name

1. In the **Tenant** list box, select the **dev01** Tenant.
2. Navigate to **Kubernetes** -> **Services**. The **Services** page displays.
3. From the **Name** column, select **demo-service**.
4. Click the **Load Balancers** tab. The ALB Load Balancer configuration is displayed.
5. In the **DNS Name** card, click **Edit**. The prefix in the DNS Name is editable.
6. Edit the **DNS Name** and select a meaningful DNS Name prefix.
7. Click **Save**. A success message briefly displays at the top center of the DuploCloud Portal.

An entry for your new DNS name is now registered with **demo-service**.

## Checking Your Work

1. Navigate to **Kubernetes** -> **Services**.
2. From the **Name** column, select **demo-service**.
3. Select the **Load Balancers** tab and verify that the **DNS Name** card displays your modified DNS Name.<br>
