Description

With my ancient minikube version (1.4.0), I had been using the option

--host-only-cidr='192.168.99.1/24'

which now gives me

X Unable to start VM. Please investigate and run 'minikube delete' if possible: driver start: Error 
setting up host only network on machine start: invalid CIDR address: '192.168.99.1/24'

with both 1.8.1 and 1.8.2. I used the option to make sure that the minikube VM gets attached to the right host-only network. It now seemed to work fine without it, so this might be no longer needed, but still...

Regards J

Contributor guide

Research direction
Inspect the CIDR validation in the driver code for host only network setup. Focus on how the ` host only cidr` option is parsed and validated. Look for recent changes that may have introduced stricter validation or a regression.
