# Connect Domain Name to Cloud DNS

IONOS Cloud DNS: connect a domain name to a Cloud DNS primary zone by updating nameservers at the registrar

{% hint style="info" %}
**Prerequisite:** You need a domain name. If you do not have one already, get a domain name and register it with a domain registrar.
{% endhint %}

To connect your domain name to the <code class="expression">space.vars.ionos\_cloud</code> primary zone that you created, specify the Cloud DNS nameservers as the domain's authoritative nameservers.

To connect a domain nameserver to a primary zone, follow these steps:

1. [<mark style="color:blue;">Create a Primary Zone</mark>](/cloud/network-services/cloud-dns/api-how-tos/create-primary-zone.md) for your domain and the associated DNS records.
2. Save the four nameservers Cloud DNS provided upon creating the primary zone.
3. Go to your Domain Registrar and update your domain's nameservers with the four nameservers from the previous step.

{% hint style="info" %}
**Note:** Changes to nameservers can take up to 48 hours, but they usually happen much faster.
{% endhint %}

{% hint style="success" %}
**Result:** The domain nameserver is connected to the Cloud DNS.
{% endhint %}

## 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.ionos.com/cloud/network-services/cloud-dns/api-how-tos/connect-domain-name-to-cloud-dns.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.
