# OVN network
<!-- Include start OVN intro -->
{abbr}`OVN (Open Virtual Network)` is a software-defined networking system that supports virtual network abstraction.
You can use it to build your own private cloud.
See [`www.ovn.org`](https://www.ovn.org/) for more information.
<!-- Include end OVN intro -->
The `ovn` network type allows to create logical networks using the OVN {abbr}`SDN (software-defined networking)`.
This kind of network can be useful for labs and multi-tenant environments where the same logical subnets are used in multiple discrete networks.
An Incus OVN network can be connected to an existing managed {ref}`network-bridge` or {ref}`network-physical` to gain access to the wider network.
By default, all connections from the OVN logical networks are NATed to an IP allocated from the uplink network.
See {ref}`network-ovn-setup` for basic instructions for setting up an OVN network.
