In hosted clusters, you can configure internal OVN subnets to avoid routing conflicts, customize network architecture, or enable virtual private cloud (VPC) peering.

Avoid CIDR conflicts:: Connect VPCs that host {product-rosa} clusters with other VPCs that use the default OVN internal subnets of 100.88.0.0/16 and 100.64.0.0/16.
Avoid CIDR conflicts:: Connect VPCs that host {product-rosa} clusters with other VPCs that use the default OVN internal subnets of 100.88.0.0/16 and 100.64.0.0/16. To avoid a conflict on a `kubevirt` hosted cluster, the HyperShift Operator sets the OVN join subnet to `100.66.0.0./16` instead of `100.64.0.0./16` or `100.65.0.0/16`. The default CIDR for the OVN gateway router is `100.64.0.0./16`. The default CIDR for the user-defined network (UDN) join subnet is `100.65.0.0/16`.
Customize network architecture:: Configure internal OVN subnets to align with your corporate network policies.
Enable VPC peering:: Deploy hosted clusters in environments where default subnets conflict with peered networks.
