# IPv4 Configuration

IONOS CLOUD VDC Networking: IPv4 address configuration and management guides

Reserve and manage static IPv4 addresses for your Virtual Data Center (VDC). <code class="expression">space.vars.ionos\_cloud</code> allows you to reserve IPv4 addresses for a fee to support your networking requirements. Using the DCD's **IP Management**, you can reserve one or more addresses from an IP block for use across your infrastructure.

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

* <code class="expression">space.vars.ionos\_cloud</code> reserves random IPv4 addresses; 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.
* An IP address can only be used in the data center region where it was reserved.
  {% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/ipv4.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.
