Query: Some good info but not well organized

There is some good info in this book but the principle criticism with is a major lack of organization of the material. It is almost as though the topics were written on little pieces of paper, thrown into a hat, and then drawn one at a time and associated to chapter 2, chapter 3, etc. For example, a discussion of binary numbers and network addressing, a preliminary topic, is left until chapter 8."VLSMs" and "IP unnumbered" are combined into one chapter. Although both topics can be thought to solve a similar problem, not much of a case is made for that. There are actually no chapters specific to routing protocols, the heart of routing. Instead, an assumption seems to be made that the reader is already familiar with routing protocols, in spite of the first chapter assuming the reader knows nothing about routing.
