CIDR prefix is smaller than /24

2020-07-08 09:04:10.860 [INFO ] [.network.internal.utils.NetworkUtils] - CIDR prefix is smaller than /24 on interface with address 10.0.34.19/16, truncating to /24, some addresses might be lost

My explicit configuration is correct. Is there a way to force the system to accept it? If not, this is a flaw.

What is your configuration?
