I find learning about Classful IPs and then learning about CIDR confusing.
When classful networks were created, were they created with the idea of subnetting in mind?
I just feel that it's wrong to read about subnetting when talking about class A networking, since referencing networks using Class A means that we are only interested in:
A) Maximum number of networks
B) Maximum number of hosts per network
When we talk of, say, x.x.x.x/18 I feel that it is more appropriate to talk about subnetting in this case, due to the prefix notation. But when I read books that mix classful IP terminology and subnetting examples / prefixes, it makes me feel like I am missing something fundamental to my understanding of how this thing is supposed to work?

Were you in a history class? IP classes have not been a thing for over 25 years. It is not necessary to know anything about them today. A book that mentions them as if they are relevant is probably only good for burning.

See this two-part answer that includes a section on network classes as the very last section of part two of the answer because network classes have been deprecated since 1993 (probably before you were born). Learn IPv4 math and subnetting before you pollute your mind with useless historical information, like network classes.
