The reader-friendly explanation of how the IP address space works and how it is used
A reader-friendly introduction to the complex and confusing topic of IP addressing
Thorough and understandable explanations of the binary mathematics behind IP addressing
Complete coverage of the IPv4 address space without distractions of routing or transport
protocols
Detailed explanations of subnetting and supernetting, Variable Length Subnet Masks (VLSMs),
CIDR, NAT, portable address spaces, and IPv6
Strategies for managing an address space for enterprise WANs, data centers, and ISPs
Numerous examples and an easy-to-read style of writing that imparts a profound understanding
of IP addressing
The Internet Protocol (IP) is the native protocol suite of the Internet and has become predominant in
virtually all networks and internetworks. Managing an IP address space requires a solid command of
binary mathematics, particularly as it is applied within the IP addressing architecture. The mathematics
of the IP address space, however, are not intuitive and can be very difficult to grasp. Consequently,
learning about IP addressing can be a lot like trying to piece together a jigsaw puzzle-but without
knowing what the puzzle is supposed to look like.
IP Addressing Fundamentals explains simply and clearly how the IP address space works and how it is
used. This is a reader-friendly book that details the fundamentals of the IP address space from the
ground up. IP Addressing Fundamentals unravels the mysteries of subnetting, supernetting, and CIDR;
thoroughly explains the binary mathematics of IPv4's addressing space; and demonstrates how an IP
address becomes an active component in both networks and internetworks. Author Mark Sportack
prepares you for real-world success by walking you through some of the issues and traps that lie in wait
for anyone who needs to plan or manage the use of an IP address space. Most importantly, this book
doesn't presume you already know what the entire IP addressing puzzle looks like.
IP Addressing Fundamentals imparts a profound command of IP addressing through a clear and
concise writing style. Basics are reinforced with detailed information and numerous examples of how the
concepts work. This book builds upon concepts presented in earlier chapters and concludes with fairly
advanced topics that will become increasingly useful to midlevel network engineers.
After reading IP Addressing Fundamentals, you'll finally understand IP addressing and appreciate both
its mechanics and relevance, and you'll know how to efficiently apply your new knowledge.
