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
which multicast group addresses have listeners on a link. The other is an addressspecific query that is used to determine whether there are listeners for a specific address on a link. The Maximum Response Delay field is used only in query messages. This is the maximum allowed delay (in milliseconds) in which a node has to send a report if it has a listener. In all other messages, this field is set to 0. The Multicast Address field is set to 0 in a general query. In an address-specific query, it
was finally overcome independently by American and British researchers. Because the British research took place within the intelligence community and was therefore classified, the American researchers Diffie, Hellman, and Merkle have been credited with overcoming the key distribution problem. Based on the idea of one-way functions operating in modular arithmetic, the next step was to devise a scheme of asymmetric encryption : instead of a shared key, a pair of mathematically related keys is used,
almost impossible to obtain enough information about the inner workings of these systems to assess whether the embedded security is up to the standards required from all other systems and applications in the organization. The complexity and openness of interfaces between the organization and entities in the outside (i.e., untrusted) world poses another problem for a coherent security environment. One financial information vendor, for instance, may give customers the choice to separate a financial
There are many production networks worldwide that have already been assigned IPv6 address prefixes. We picked four examples of companies that made their step into the future by offering IPv6 services. 22.214.171.124 vBNS+ vBNS+ is a specialized US IP network that supports high-performance, high-bandwidth applications. The vBNS+ network supports both native IPv6-over-ATM connections and tunneled IPv6-in-IPv4 connections. The vBNS+ service has been assigned its own sTLA from ARIN, as well as a pTLA for
Address Prefix. The Prefix Length defines the length of the address prefix. Table 8-8 explains the prefix options. The Address Prefix represents the IPv6 address. If necessary, it is padded with zero bits to the next full 32-bit word. 126.96.36.199 Intra-Area-Prefix-LSA (Type 0x2009) A router uses the Intra-Area-Prefix-LSA to advertise one or more IPv6 prefixes associated with either this router or a Network-LSA. As OSPF for IPv6 has removed all addressing semantics from the Router-LSAs and
