You explained the math behind subnetting, but you never explained what it was used for. A more in-depth explanation of this would be more useful.

The small paragraph were you explain about network portions, class B is correct.

Please check Class A&C, you nominate the network portion as hosts.

I also dont understand this as first and second set of usable address ranges make no sense to me. Surely 5 bits would be adding up 128 + 64 + 32 + 16 + 8. Makes no sense at all.

Hi,

How do you borrow 5 bits from the host if it's all 0's?
would it not be
10011100.00000001- network.11000000.11100000- host
