OK, not getting it, so I will try and ask in a different way.

First, which octet changes in a an IP subnet range, the network octet or the host octet ?

What's your definition of an "octet"?

If its an 8-bit-byte: again, forget the octet. As you can see in your request, subnets can be defined by the bit like your teachers do with /18 and /22. Then, within the subnet definition, the network part is just counted up one by one to skim through the subnets.

Just wanted to understand this, is it safe to say that the second subnet starts after the broadcast address:

192.168.0.0 /22
255.255.252.0
192.168.0.0 – 192.168.(3).255(Broadcast address)
192.168.(4).0 – 192.168.(7).255(Broadcast address), then next subnet
192.168.(8).0 – 192.168.(11).255(Broadcast address), then next subnet
192.168.(12).0 – 192.168.(15).255(Broadcast address)
And so on...

Similarly for the below IP:

IP Address – 172.59.0.0
Custom Subnet Mask – 255.255.252.0
Broadcast Address – 172.59.3.255

172.59.0.0 - 172.59.3.255
172.59.4.0 - 172.59.7.255
172.59.8.0 - 172.59.11.255
172.59.12.0 - 172.59.15.255
And so on....

Yes. The broadcast address (or all-ones address) is the last in the range by definition.
