In ICND 1 course, I was taught that I can classify IP Address as following:
Public -> Static, Dynamic(DHCP)
Private
This is how I classifies:
Public -> Static, Dynamic(NAT)
Private -> Static, Dynamic(DHCP, APIPA)
Lastly, this is how my friend classifies:
Public -> Static(Non RFC-1918), Dynamic(DHCP, NAT)
Private -> Static(RFC-1918), Dynamic(DHCP, APIPA)
-> I would like to know which one is the most accurate way to classify IP Address.
Lastly, is 192.23.32.x/24 C-class network? I strongly believe that 192.23.32.x/24 must not be called as C-class network since there is a prefix. "Prefix"simply represents that this IP address doesn't have a concept of "CLASS" anymore. Still, some people call it C-class network. I am pretty lost at this point, so please let me know if you are 100% sure about this problem \^0^/

Hello,
I´d say that your friend´s classification is more accurated then yours.
Public -> Static, Dynamic(NAT)
NAT is not a definition of IP in terms of Dynamic considering that NAT also take in consideration Ports which is Layer 4.
I think Static, Dynamic(DHCP) is better. Public IP also can be provided by DHCP.
Private -> Static, Dynamic(DHCP, APIPA)
This is ok.
192.23.32.x/24 can be classified as Class C. Yes, it has a prefix and this allows us to identify which part is reserved for Host and which part can be used for Network.
The basic definition of class C is any IP range between 192.x.x.x up to 223.x.x.x
Hope that helps.

I just use public and private to describe IPs, anything else just complicates it.
Yes it is class C but note nowadays we talk more in / notation.
