A step-by-step guide to managing critical technologies of today's converged services IP networks Effective IP Address Management (IPAM) has become crucial to maintaining high-performing IP services such as data, video, and voice over IP. This book provides a concise introduction to the three core IPAM networking technologies—IPv4 and IPv6 addressing, Dynamic Host Configuration Protocol (DHCP), and Domain Name System (DNS)—as well as IPAM practice and techniques needed to manage them cohesively. The book begins with a basic overview of IP networking, including a discussion of protocol layering, addressing, and routing. After a review of the IPAM technologies, the book introduces the major components, motivation, benefits, and basic approaches of IPAM. Emphasizing the necessity of a disciplined "network management" approach to IPAM, the subsequent chapters enable you to: Understand IPAM practices, including managing your IP address inventory and tracking of address transactions (such as allocation and splitting address space, discovering network occupancy, and managing faults and performance) Weigh the costs and justifications for properly implementing an IPAM strategy Use various approaches to automating IPAM functions through workflow Learn about IPv4-IPv6 co-existence technologies and approaches Assess security issues with DHCP network access control approaches and DNS vulnerabilities and mitigation including DNSSEC Evaluate the business case for IPAM, which includes derivation of the business case cost basis, identification of savings when using an IP address management system, associated costs, and finally net results Introduction to IP Address Management concludes with a business case example, providing a real-world financial perspective of the costs and benefits of implementing an IP address management solution. No other book covers all these subjects cohesively from a network management perspective, which makes this volume imperative for manager-level networking professionals who need a broad understanding of both the technical and business aspects of IPAM. In addition, technologists interested in IP networking and address management will find this book valuable.

This book will be the first covering the subject of IP address management (IPAM). The practice of IPAM includes the application of network management disciplines to IP address space and associated network services, namely DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name System). The consequence of inaccurately configuring DHCP is that end users may not be able to obtain IP addresses to access the network. Without proper DNS configuration, usability of the network will greatly suffer as the name-to-address lookup process may fail. Imagine having to navigate to a website or send an email or an instant message by IP address instead of by name! It's equally important that these DHCP and DNS configurations be based on a common IP address plan, which maps out the IP address hierarchy, subnets, address pools, and domains. IPAM applies management disciplines to these core services, including configuration, change control, auditing, reporting and so on, and they are necessary given the absolute requirement for properly managing IP space and DHCP and DNS servers. The linkages among an IP address plan, DHCP server configuration and DNS server configuration are inseparable; a change of an IP address will affect DNS information and perhaps DHCP as well. These functions provide the foundation for today's converged services IP networks, so they need to be managed using a rigorous approach. Today, there is no single book that covers the management of these linkages and services they provide; IP Address Management Principles and Practice will fill that gap. While several books are available for leading vendors' DHCP and DNS services implementations, few exist for IP address planning, and none exist that unifies these three topics.

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.
