# DCD How-Tos

You can configure a Cross Connect via the DCD and associate it with multiple VDCs to establish a connection between them via a private LAN.

## Prerequisites

* Contract owners and administrators can create, access, manage, and use Cross Connect without additional permissions. However, non-admin users need relevant access to create and manage Cross Connect. For more information, see [<mark style="color:blue;">Set Up User Privileges for Cross Connect</mark>](https://docs.ionos.com/sections-test/guides/network-services/cross-connect/how-tos/set-privileges-cross-connect).
* Before you connect data centers, ensure they:
  * belong to the same region and contract. Prior to connecting, remember to provision your data centers.
  * have the same IP address range.
* Ensure that the [<mark style="color:blue;">IP address</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#internet-protocol-ip-address) is tied to only one instance.
* The LANs to be used for the connection should be private LANs. The private [<mark style="color:blue;">NICs</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#network-interface-card-nic) to be connected should have unique IP addresses that belong to the same IP range.
