tpu
Deprecated
The IP address range of the Cloud TPUs in this cluster. If unspecified, a range will be automatically chosen with the default size. This field is only applicable when `use_ip_aliases` is true. If unspecified, the range will use the default size. Set to /netmask (e.g. `/14`) to have a range chosen with a specific netmask. Set to a [CIDR](http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing) notation (e.g. `10.96.0.0/14`) from the RFC-1918 private networks (e.g. `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16`) to pick a specific range to use. This field is deprecated, use cluster.tpu_config.ipv4_cidr_block instead.
