If your existing network infrastructure overlaps with the `100.64.0.0/16` IPv4 subnet, you can specify a different IP address range for internal use by OVN-Kubernetes. You must ensure that the IP address range does not overlap with any other subnet used by your {product-title} installation. The IP address range must be larger than the maximum number of nodes that can be added to the cluster.

For example, if the `clusterNetwork.cidr` is `10.128.0.0/14` and the `clusterNetwork.hostPrefix` is `/23`, then the maximum number of nodes is `2^(23-14)=128`. An IP address is also required for the gateway, network, and broadcast addresses. Therefore the internal IP address range must be at least a `/24`.

An IP address is also required for the gateway, network, and broadcast addresses. Therefore the internal IP address range must be at least a `/24`.
