# FAQ

### What is Cross Connect?

Cross Connect is a feature designed to connect multiple VDCs in the same region and contract using a private LAN. With Cross Connect, you can ensure safe data passage between the VDCs, reduce latency and improve performance compared to public connectivity.

### What are the benefits of Cross Connect?

Cross Connects are reliable and resistant to network congestion as the data transfers quickly between the connected VDCs. In addition, it facilitates resource sharing between the connected VDCs, reducing the cost of redundant virtual infrastructure setups. For additional benefits offered by Cross Connect, see [<mark style="color:blue;">Overview</mark>](https://docs.ionos.com/sections-test/guides/network-services/cross-connect/overview).

### Can I connect VDCs across regions via Cross Connect?

No, currently Cross Connect enables you to connect VDCs within a region. For example, you can connect multiple VDCs in Berlin, but you cannot connect a VDC that is in Frankfurt. Note that the NICs of the VDCs must belong to the same IP address range.

### Can I upgrade my existing Cross Connect to the latest version?

The upgraded version of the feature allows you to connect all VDCs within the same region. Also, the previous version of the product will be deprecated in the future.
