= Known limitations for internal subnets for hosted clusters

[role="_abstract"]
Several known limitations exist for internal subnets on hosted clusters.

* IPv6 subnets are not supported.
* The {hcp} command-line interface, `hcp`, might not have native flags for the subnet fields. Manual YAML editing or `oc patch` is required.
* Modifying OVN subnets after you create a cluster triggers a rollout of OVN components, which might cause brief network disruptions.
* You cannot modify OVN subnet configuration while a cluster update is in progress or scheduled.
