Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am trying to understand networking and have a few questions. Please feel free to correct me If I am wrong.
A Class B network has a netmask of 255.255.0.0, therefore there are 2 octets reserved for the host part. Question: If two hosts, with xxx.xxx.5.2 and xxx.xxx.4.6 IP address belong to the same class B network xxx.xxx.0.0, then can they see each other without a router in between them? (Or must all the first three octets match before a host can see another host?).
I can use subnetting to divide a network into smaller segments by using the letfmost bits of the host for subnetting. Subnets cannot see other subnets without a router. Therefore, when configuring subnets, I will have 3 less addresses that I can use for hosts : one address is used for the subnet address (the lowest host number), one address is used for the router (typically the host next higher to the lowest host number), and one for the broadcast address (the highest host number in the subnet).
I suggest looking through all of the ipprimer if you want a good foundation of network. It's pretty thorough. If you wanna get into networking logistics hardcore, then I highly suggest TCP/IP Illustrated by W. Richard Stevens. Great book that comes in a couple volumes. Start with Volume 1.
