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'saddressing 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.

Editorial Reviews

The Barnes & Noble Review
Why do so many people find IP addressing so hard? Maybe it’s because most writers on the subject dive headfirst into the details, without explaining how the entire system fits together. Maybe they think you already know that. (Maybe they don’t understand it!) No matter. Read IP Addressing Fundamentals and you’ll understand this stuff well enough to teach it.

Which is exactly what author Mark A. Sportack does for a living. Here, he gives you the “big picture,” shows how every element fits into the overall system, and explains why IP addressing has evolved as it has -- full of “stopgap” solutions that now seem permanent.

He begins with “classical IP,” subnet masks, supernetting, NAT, and especially CIDR, which bridged the gaps between network classes, delaying address depletion and making routing tables more manageable. Once you’re rock-solid on the basics, Sportack offers a concise, readable introduction to DNS, then introduces IPv4 multicasting with IGMPv1 and v2.

Part III focuses on strategies for maximizing network stability, scalability, and performance. Sportack starts by explaining what actually happens when an Ethernet LAN user contacts an external web site: how Ethernet addresses are translated to IP, and how routers use them to calculate routes. You’ll learn how to ameliorate vulnerabilities in IP-based networks; and, especially, how to plan and manage address spaces. Shortack wraps up with the fairest, simplest explanation of IPv6 we’ve seen -- thankfully, without taking sides in the IPv6 “religious war.”

What a shame it took so long to get an IP book this accessible. Bill Camarda
