If I understand your question correctly
These are incorrect. You have the right idea, but these are 18 bit networks.170.50.0.0 – 170.50.63.255
170.50.64.0 – 170.50.127255
170.50.128.0 – 170.50.191.255
170.50.192.0 – 170.50.255.255
These look correct:170.50.1.0 - – 170.50.1.63
170.50.1.64 – 170.50.1.127
170.50.1.128 – 170.50.1.191
170.50.1.192 – 170.50.1.255 -

Those are right. If you want ranges from your example in C to work, you need a 255.255.192.0 mask.:study:Reading: Lab Books, Ansible Documentation, Python Cookbook 2018 Goals: More Ansible/Python work for Automation, IPSpace Automation Course [X], Build Jenkins Framework for Network Automation [] -
