# DCD How-Tos

{% hint style="info" %}
**Prerequisites:**

Prior to enabling IPv6, make sure you have the appropriate privileges. New Virtual Data Center (VDC) can be created by the contract owners, administrators, or users with create VDC privilege. The leading number of bits in the address that cannot be changed is the **prefix length**. For Data Center IPv6 CIDR, the prefix length is **/56**.
{% endhint %}

You can enable the IPv6 LAN and configure the network to support IPv6. Using IPv6 LANs, devices can communicate on the same LAN using standard IPv6 protocols. IONOS LANs route packets between devices and networks, ensuring that the network runs smoothly and effectively.
