Ip Addressing Fundamentals

Finally, there's a non-theoretical, practical primer on all the basics of IP networking -- perfect for Web professionals, LAN managers, MIS managers, application developers, network administrators, and ISPs. This hands-on guide teaches all the fundamentals of IP addressing, routing, and troubleshooting -- with real-world exercises and examples throughout. The book contains broad coverage of the IP protocol itself; how IP operates over Ethernet, Token Ring, ATM, FDDI, and Frame Relay; the interplay between addressing and routing; OSPF; BGP-4 and its implications for edge customers; routing protocol interactions; techniques for minimizing and simplifying import/export; and more.

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.

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.

From Charles M. Kozierok, the creator of the highly regarded www.pcguide.com, comes The TCP/IP Guide. This completely up-to-date, encyclopedic reference on the TCP/IP protocol suite will appeal to newcomers and the seasoned professional alike. Kozierok details the core protocols that make TCP/IP internetworks function and the most important classic TCP/IP applications, integrating IPv6 coverage throughout. Over 350 illustrations and hundreds of tables help to explain the finer points of this complex topic. The book’s personal, user-friendly writing style lets readers of all levels understand the dozens of protocols and technologies that run the Internet, with full coverage of PPP, ARP, IP, IPv6, IP NAT, IPSec, Mobile IP, ICMP, RIP, BGP, TCP, UDP, DNS, DHCP, SNMP, FTP, SMTP, NNTP, HTTP, Telnet, and much more. The TCP/IP Guide is a must-have addition to the libraries of internetworking students, educators, networking professionals, and those working toward certification.

The perimeter defenses guarding your network perhaps are not as secure as you think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. That’s an all-too-familiar scenario today. With this practical book, you’ll learn the principles behind zero trust architecture, along with details necessary to implement it. The Zero Trust Model treats all hosts as if they’re internet-facing, and considers the entire network to be compromised and hostile. By taking this approach, you’ll focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. Understand how perimeter-based defenses have evolved to become the broken model we use today Explore two case studies of zero trust in production networks on the client side (Google) and on the server side (PagerDuty) Get example configuration for open source tools that you can use to build a zero trust network Learn how to migrate from a perimeter-based network to a zero trust network in production

The definitive introduction to routing, demystifying routers by exploring the mechanics, routing protocols, network interfaces, and operating systems. The book teaches how routers can be used in today's networks, as well as how they will be used in the future.
