# Program DNS Entries

Add DNS entries for DuploCloud Services to use your domain names

If you plan to use custom domain names with DuploCloud-hosted services, a subdomain-hosted zone must be created to program DNS entries so DuploCloud services can access them. Public and private DNS zones are supported. In addition, keys must be added to the DuploCloud configuration that map to the required DNS entries. To complete these tasks, contact DuploCloud via email or by using your private Slack channel. Our support staff will assist you in completing this and other prerequisites.

Once the DNS entries are configured, you can use your existing domain names with DuploCloud.

For more info about DNS setup and custom DNS names, see the [DNS Configuration documentation](/docs/automation-platform/duplocloud-prerequisites/resolving-dns-failures.md).

{% hint style="warning" %}
In order to add your DNS entries, contact DuploCloud via email or by using your private Slack channel. Our support staff guides you through the process and assists you with completing other prerequisites in this section, such as providing CRT files and private keys for [importing SSL certificates](/docs/automation-platform/overview-2/prerequisites/import-ssl-certificates.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.duplocloud.com/docs/automation-platform/overview-2/prerequisites/program-dns-entries.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
