  • Thanks for the upload… is 2023 and my professor is teaching it the same way .

  • Why are you discussing something that's been obsolete for almost 30 years? Classless Inter-Doamain Routing (CIDR) superceded address classes in 1993. Also, what was class E is now reserved for future use. You should be talking about CIRD and variable length subnets instead. Also, the solution to the IPv4 address shortage, is not private addresses and NAT. It's IPv6 which has an unbelievably huge address space. NAT is a hack that causes other problems.
