Anyone who is involved with information technology knows that the Internet is running out of IP addresses. The last block of Internet Protocol version 4 (IPv4) addresses was allocated in 2011. Internet Protocol version 6 (IPv6) is the replacement for IPv4, and it is designed to address the depletion of IP addresses and change the way traffic is managed. This IBM® RedpaperTM publication describes the concepts and architecture of IPv6 with a focus on: An overview of IPv6 features An examination of the IPv6 packet format An explanation of additional IPv6 functions A review of IPv6 mobility applications This paper provides an introduction to Internet Control Message Protocol (ICMP) and describes the functions of ICMP in an IPv6 network. This paper also provides IPv6 configuration steps for the following clients: Microsoft Windows Red Hat Enterprise Linux IBM AIX® VMware vSphere ESXi 5.0 After understanding the basics of IPv6 concepts and architecture, IT network professionals will be able to use the procedures outlined in this paper to configure various host operating systems to suit their network infrastructure.

To support future business continuity, growth, and innovation, organizations must transition to IPv6, the next generation protocol for defining how computers communicate over networks. IPv6 Fundamentals provides a thorough yet easy-to-understand introduction to the new knowledge and skills network professionals and students need to deploy and manage IPv6 networks. Leading networking instructor Rick Graziani explains all the basics simply and clearly, one step at a time, providing all the details you''ll need to succeed. Building on this introductory coverage, he then introduces more powerful techniques that involve multiple protocols and processes and provides hands-on resources you can rely on for years to come. You''ll begin by learning why IPv6 is necessary, how it was created, and how it works. Next, Graziani thoroughly introduces IPv6 addressing, configuration options, and routing protocols, including RIPng, EIGRP for IPv6, and OSPFv3. You''ll learn how to integrate IPv6 with IPv4, enabling both protocols to coexist smoothly as you move towards full reliance on IPv6. Throughout, Graziani presents all the IOS command syntax you''ll need, offering specific examples, diagrams, and Cisco-focused IPv6 configuration tips. You''ll also find links to Cisco white papers and official IPv6 RFCs that support an even deeper understanding. Rick Graziani teaches computer science and computer networking courses at Cabrillo College. He has worked and taught in the computer networking and IT field for nearly 30 years, and currently consults for Cisco and other leading clients. Graziani''s recent Cisco Networking Academy Conference presentation on IPv6 Fundamentals and Routing drew a standing audience and the largest virtual audience for any session at the event.

If your organization is gearing up for IPv6, this in-depth book provides the practical information and guidance you need to plan for, design, and implement this vastly improved protocol. Author Silvia Hagen takes system and network administrators, engineers, and network designers through the technical details of IPv6 features and functions, and provides options for those who need to integrate IPv6 with their current IPv4 infrastructure. The flood of Internet-enabled devices has made migrating to IPv6 a paramount concern worldwide. In this updated edition, Hagen distills more than ten years of studying, working with, and consulting with enterprises on IPv6. It’s the only book of its kind. IPv6 Essentials covers: Address architecture, header structure, and the ICMPv6 message format IPv6 mechanisms such as Neighbor Discovery, Stateless Address autoconfiguration, and Duplicate Address detection Network-related aspects and services: Layer 2 support, Upper Layer Protocols, and Checksums IPv6 security: general practices, IPSec basics, IPv6 security elements, and enterprise security models Transitioning to IPv6: dual-stack operation, tunneling, and translation techniques Mobile IPv6: technology for a new generation of mobile services Planning options, integration scenarios, address plan, best practices, and dos and don’ts

This is a guide to deploying IPv6 in any campus, WAN/branch, or data center environment. It shows the reader how to review, compare, and choose the right IPv6 implementation options, how to to understand IPv6 services and the features that make them possible, and how to plan, deploy and manage IPv6 services in IPv4 networks.

IPv6 Security Protection measures for the next Internet Protocol As the world’s networks migrate to the IPv6 protocol, networking professionals need a clearer understanding of the security risks, threats, and challenges this transition presents. In IPv6 Security, two of the world’s leading Internet security practitioners review each potential security issue introduced by IPv6 networking and present today’s best solutions. IPv6 Security offers guidance for avoiding security problems prior to widespread IPv6 deployment. The book covers every component of today’s networks, identifying specific security deficiencies that occur within IPv6 environments and demonstrating how to combat them. The authors describe best practices for identifying and resolving weaknesses as you maintain a dual stack network. Then they describe the security mechanisms you need to implement as you migrate to an IPv6-only network. The authors survey the techniques hackers might use to try to breach your network, such as IPv6 network reconnaissance, address spoofing, traffic interception, denial of service, and tunnel injection. The authors also turn to Cisco® products and protection mechanisms. You learn how to use Cisco IOS® and ASA firewalls and ACLs to selectively filter IPv6 traffic. You also learn about securing hosts with Cisco Security Agent 6.0 and about securing a network with IOS routers and switches. Multiple examples are explained for Windows, Linux, FreeBSD, and Solaris hosts. The authors offer detailed examples that are consistent with today’s best practices and easy to adapt to virtually any IPv6 environment.
