Custom VPC Subranges for New GCP Databricks Deployment

[mnorland]

What Pods and Services subranges would you recommend for a /22 subnet for a custom VPC for a new GCP Databricks deployment in the GCE era?

The secondary ranges are there to support legacy GKE clusters.  While required in the UI, they can be empty in terraform (per a source) for new deployments as clusters are GCE now. (There is a green GCE next to the cluster name.)  When observing the cluster spin up in GCE, there are two IP addresses per VM and they all are from the primary range.
