 For Kubernetes clusters, these parameters are specified in the StorageClass.
 
 Note that non-default networks require extra [firewall setup](https://cloud.google.com/filestore/docs/configuring-firewall)
 
 ## Future Features
-* Reserved IP range: To avoid IP conflict issues, add a CreateVolume parameter
-  to provide an IP block that is reserved for dynamically provisioning GCFS instances.
 * Non-root access: By default, GCFS instances are only writable by the root user
   and readable by all users. Provide a CreateVolume parameter to set non-root
   owners.
