Chapter 13. Analyzing Classful IPv4 Networks


This chapter covers the following subjects:

Classful Network Concepts: This section examines the ideas related to Class A, Class B, and Class C networks (in other words, classful IP networks).

Practice with Classful Networks: This section helps readers prepare for the CCENT and CCNA exams by listing practice problems, tips, and suggestions for how to better review the math and logic used to analyze classful networks.


When operating a network, you often start investigating a problem based on an IP address and mask. Based on the IP address alone, you should be able to determine several facts about the Class A, B, or C network in which the IP address resides. These facts can be useful when troubleshooting some networking problems.
