# IP Addresses

IONOS CLOUD VDC Networking: manage IPv4 and IPv6 addresses for virtual data centers

If you want to build a network using static [<mark style="color:blue;">IP addresses</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#ip-address), <code class="expression">space.vars.ionos\_cloud</code> offers you the option to reserve IPv4 addresses for a fee. You can reserve one or more addresses in an IP block using the [<mark style="color:blue;">DCD's</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#dcd) **IP Management**.

An IP address can only be used in the data center from the region where it was reserved. Therefore, if you need an IP address for your virtual data center in Frankfurt, you should reserve the IP address there. Each IP address can only be used once, but different IP addresses from a block can be used in different networks, provided these networks are provisioned in the same region where the IP block is located.

{% hint style="warning" %}
**Important:**

* <code class="expression">space.vars.ionos\_cloud</code> reserves random IP address, you cannot reserve a specific IPv4 address.
* Reserving and using IPv4 addresses is restricted to authorized users only. Contract owners and administrators may grant privileges to reserve IP addresses.
  {% 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/vdc-networking/ip-address.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.
