+  Set this to "false" to keep the primary IPs bound to your Hetzner-Account, even after a destroy.
+  This setting would allow for reuse of the same IPs between multiple create/destroy cycles.
+  Though, it doesn't guarantee reuse of the same IPs.

+  Note, that reserved IPs will create costs, even if they're not used.
