# Cross Connects

Cross Connect allows you to connect virtual data centers (VDC) with each other using a private LAN. The VDCs to be connected need to belong to the same IONOS CLOUD contract and location. You can only use private LANs for a Cross Connect connection. A LAN can only be a part of one Cross Connect.

The IP addresses of the NICs used for the Cross Connect connection may not be used in more than one NIC and they need to belong to the same IP range.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ionos.com/cloud/api-reference/cloud-api-v6/cross-connects.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
