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.

DNS Security: Defending the Domain Name System provides tactics on how to protect a Domain Name System (DNS) framework by exploring common DNS vulnerabilities, studying different attack vectors, and providing necessary information for securing DNS infrastructure. The book is a timely reference as DNS is an integral part of the Internet that is involved in almost every attack against a network. The book focuses entirely on the security aspects of DNS, covering common attacks against DNS servers and the protocol itself, as well as ways to use DNS to turn the tables on the attackers and stop an incident before it even starts. - Presents a multi-platform approach, covering Linux and Windows DNS security tips - Demonstrates how to implement DNS Security tools, including numerous screen shots and configuration examples - Provides a timely reference on DNS security, an integral part of the Internet - Includes information of interest to those working in DNS: Securing Microsoft DNS and BIND servers, understanding buffer overflows and cache poisoning, DDoS Attacks, pen-testing DNS infrastructure, DNS firewalls, Response Policy Zones, and DNS Outsourcing, amongst other topics

Rediscover fundamental and advanced topics in IPAM, DNS, DHCP and other core networking technologies with this updated one-stop reference The thoroughly revised second edition of IP Address Management is the definitive reference for working with core IP management technologies, like address allocation, assignment, and network navigation via DNS. Accomplished professionals and authors Timothy Rooney and Michael Dooley offer readers coverage of recent IPAM developments in the world of cloud computing, Internet of Things (IoT), and security, as well as a comprehensive treatment of foundational concepts in IPAM. The new edition addresses the way that IPAM needs and methods have evolved since the publication of the first edition. The book covers the impact of mainstream use of private and public cloud services, the maturation of IPv6 implementations, new DNS security approaches, and the proliferation of IoT devices. The authors have also reorganized the flow of the book, with much of the technical reference material appearing at the end and making for a smoother and simpler reading experience. The 2nd edition of IP Address Management also covers topics like such as: Discussions about the fundamentals of Internet Protocol Address Management (IPAM), including IP addressing, address allocation and assignment, DHCP, and DNS An examination of IPAM practices, including core processes and tasks, deployment strategies, IPAM security best-practices, and DNS security approaches A treatment of IPAM in the modern context, including how to adapt to cloud computing, the Internet of Things, IPv6, and new trends in IPAM A one-stop reference for IPAM topics, including IP addressing, DHCP, DNS, IPv6, and DNS security Perfect for IP network engineers and managers, network planners, network architects, and security engineers, the second edition of IP Address Management also belongs on the bookshelves of senior undergraduate and graduate students studying in networking, information technology, and computer security-related courses and programs.

This book will give you an all encompassing view of the domain name ecosystem combined with a comprehensive set of operations strategies. Key Features Manage infrastructure, risk, and management of DNS name servers. Get hands-on with factors like types of name servers, DNS queries and and so on. Practical guide for system administrators to manage mission-critical servers Based on real-world experience - Written by an industry veteran who has made every possible mistake within this field. Book Description Managing your organization's naming architecture and mitigating risks within complex naming environments is very important. This book will go beyond looking at “how to run a name server” or “how to DNSSEC sign a domain”, Managing Mission Critical Domains & DNS looks across the entire spectrum of naming; from external factors that exert influence on your domains to all the internal factors to consider when operating your DNS. The readers are taken on a comprehensive guided tour through the world of naming: from understanding the role of registrars and how they interact with registries, to what exactly is it that ICANN does anyway? Once the prerequisite knowledge of the domain name ecosystem is acquired, the readers are taken through all aspects of DNS operations. Whether your organization operates its own nameservers or utilizes an outsourced vendor, or both, we examine the complex web of interlocking factors that must be taken into account but are too frequently overlooked. By the end of this book, our readers will have an end to end to understanding of all the aspects covered in DNS name servers. What you will learn Anatomy of a domain - how a domain is the sum of both its DNS zone and its registration data, and why that matters. The domain name ecosystem - the role of registries, registrars and oversight bodies and their effect on your names. How DNS queries work - queries and responses are examined including debugging techniques to zero in on problems. Nameserver considerations - alternative nameserver daemons, numbering considerations, and deployment architectures. DNS use cases - the right way for basic operations such as domain transfers, large scale migrations, GeoDNS, Anycast DNS. Securing your domains - All aspects of security from registrar vendor selection, to DNSSEC and DDOS mitigation strategies. Who this book is for Ideal for sysadmins, webmasters, IT consultants, and developers-anyone responsible for maintaining your organization's core DNS

A Practical Introduction to Enterprise Network and Security Management, Second Edition, provides a balanced understanding of introductory and advanced subjects in both computer networking and cybersecurity.
