Use a private network range for Pod CIDR #29

Closed hoeghh closed 6 years ago

hoeghh commented 6 years ago

The network range 20.0.0.0/16 is in the public network area (this is owned by Microsoft)

https://en.wikipedia.org/wiki/Private_network

In time, this should be configurable in the config file

hoeghh commented 6 years ago

Maybe use the range 172.16.0.0/12 . Test, and if it works, replace the current address space.
