Organizations are increasingly transitioning to IPv6, the next generation protocol for defining how devices of all kinds communicate over networks. Now fully updated, IPv6 Fundamentals offers a thorough, friendly, and easy-to-understand introduction to the knowledge and skills you need to deploy and operate IPv6 networks. Leading networking instructor Rick Graziani explains all the basics simply and clearly, step-by-step, providing all the details you'll need to succeed. You'll learn why IPv6 is necessary, how it was created, how it works, and how it has become the protocol of choice in environments ranging from cloud to mobile and IoT. Graziani thoroughly introduces IPv6 addressing, configuration options, and routing protocols, including EIGRP for IPv6, and OSPFv3 (traditional configuration and with address families). Building on this coverage, he then includes more in-depth information involving these protocols and processes. This edition contains a completely revamped discussion of deploying IPv6 in your network, including IPv6/IPv4 integration, dynamic address allocation, and understanding IPv6 from the perspective of the network and host. You'll also find improved coverage of key topics such as Stateless Address Autoconfiguration (SLAAC), DHCPv6, and the advantages of the solicited node multicast address. Throughout, Graziani presents command syntax for Cisco IOS, Windows, Linux, and Mac OS, as well as many examples, diagrams, configuration tips, and updated links to white papers and official RFCs for even deeper understanding. Learn how IPv6 supports modern networks encompassing the cloud, mobile, IoT, and gaming devices Compare IPv6 with IPv4 to see what has changed and what hasn't Understand and represent IPv6 addresses for unicast, multicast, and anycast environments Master all facets of dynamic IPv6 address allocation with SLAAC, stateless DHCPv6, and stateful DHCPv6 Understand all the features of deploying IPv6 addresses in the network including temporary addresses and the privacy extension Improve operations by leveraging major enhancements built into ICMPv6 and ICMPv6 Neighbor Discovery Protocol Configure IPv6 addressing and Access Control Lists using a common topology Implement routing of IPv6 packets via static routing, EIGRP for IPv6, and OSPFv3 Walk step-by-step through deploying IPv6 in existing networks, and coexisting with or transitioning from IPv4

DNS & BIND im IPv6 - kurz & gut enthält das ganze Material zu IPv6. Es behandelt, wie DNS erweitert wurde, um IPv6-Adressen gerecht zu werden, sowohl für das Forward-Mapping als auch für das Reverse-Mapping. Es beschreibt, wie man einen BIND-Nameserver so konfiguriert, dass er in einem IPv6-Netzwerk läuft, und wie man Probleme mit dem IPv6-Forward- und Reverse-Mapping behebt. Es behandelt sogar DNS64, eine DNS-basierte Übergangstechnik, die – zusammen mit einer Partnertechnik namens NAT64 – Inseln aus Hosts, die nur IPv6 sprechen, dabei helfen, mit IPv4-Ressourcen zu kommunizieren. Dieses Buch beschreibt, wie IPv6 in Netzwerken mit DNS unterstützt wird. Es behandelt die zugrundeliegende Theorie, einschließlich der Struktur und der Repräsentation der IPv6-Adressen, der A-, M- und O-Flags in Router-Advertisements und was sie für DNS bedeuten, sowie die Syntax der AAAA-Records und der PTR-Records in der ip6.arpa-Reverse-Mapping-Zone und die Syntax und Semantik der Konfiguration eines BIND-Nameservers. DNS & BIND im IPv6 - kurz & gut geht davon aus, dass Sie die grundlegende DNS-Theorie und BIND-Konfiguration verstehen. Es erklärt nicht, was ein Resource Record ist, wie man eine Zonendatendatei bearbeitet, noch erinnert es Sie daran, dass Sie die Seriennummer des SOA-Records einer Zone erhöhen müssen, bevor Sie ihn neu laden. Das Buch geht aber nicht davon aus, dass Sie irgendetwas über IPv6 wissen. Vielmehr erläutert es die Motivation für den Wechsel zu IPv6 und beschreibt die Struktur und die Darstellung von IPv6-Adressen und wie man BIND-Nameserver für den Betrieb in IPv6-Netzwerken konfiguriert.

Be more productive and make your life easier. That's what LDAP System Administration is all about. System administrators often spend a great deal of time managing configuration information located on many different machines: usernames, passwords, printer configurations, email client configurations, and network filesystem configurations, to name a few. LDAPv3 provides tools for centralizing all of the configuration information and placing it under your control. Rather than maintaining several administrative databases (NIS, Active Directory, Samba, and NFS configuration files), you can make changes in only one place and have all your systems immediately "see" the updated information. Practically platform independent, this book uses the widely available, open source OpenLDAP 2 directory server as a premise for examples, showing you how to use it to help you manage your configuration information effectively and securely. OpenLDAP 2 ships with most Linux® distributions and Mac OS® X, and can be easily downloaded for most Unix-based systems. After introducing the workings of a directory service and the LDAP protocol, all aspects of building and installing OpenLDAP, plus key ancillary packages like SASL and OpenSSL, this book discusses: Configuration and access control Distributed directories; replication and referral Using OpenLDAP to replace NIS Using OpenLDAP to manage email configurations Using LDAP for abstraction with FTP and HTTP servers, Samba, and Radius Interoperating with different LDAP servers, including Active Directory Programming using Net::LDAP If you want to be a master of your domain, LDAP System Administration will help you get up and running quickly regardless of which LDAP version you use. After reading this book, even with no previous LDAP experience, you'll be able to integrate a directory server into essential network services such as mail, DNS, HTTP, and SMB/CIFS.

Therefore, understanding the technology and being able to plan, design, and deploy IPv6 services are necessary skills for networking professionals. Deploying IPv6 Networks is an essential guide to IPv6 concepts, service implementation, and interoperability in existing IPv4 environments. You'll learn about IPv6 as a mature technology ready for deployment. Deploying IPv6 Networks goes beyond addressing the basics of IPv6 yet remains accessible to readers unfamiliar with the protocol. With this book in hand, you will learn how to plan, design, deploy, and manage IPv6 services. Deploying IPv6 Networks opens with an updated "Case for IPv6": a review of the IPv4 challenges and the IPv6 opportunities. It then covers the IPv6 concepts related to IP services provided in real networks. Relevant features and corresponding configuration examples are presented in a deployment context as they are applied to the various segments of the network. The IPv6 knowledge accumulated in the first part of the book is revisited in Part II, where it is leveraged in concrete and usable examples that cover most common network environments: MPLS service provider, IP service provider, and enterprise. The structure of Deploying IPv6 Networks enables you to use it as a reference for specific aspects of IPv6, as a technology study guide, or as a design guide for deploying IPv6. You'll also find that the presentation approach enables you to leverage your IPv4 experience to quickly become knowledgeable and proficient with the concepts of IPv6.

Studienarbeit aus dem Jahr 2004 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,3, Universitat Mannheim (Informatik), Veranstaltung: Rechnernetze, 5 Quellen im Literaturverzeichnis, Sprache: Deutsch, Abstract: Die Entwicklung des IPv4 (Internet Protocol version 4) Protokolls als Standard fur den Internet-Vorlaufer ARPANet erfolgte Anfang der 80er Jahre und liegt damit uber 20 Jahre zuruck. Seither hat das Wachstum des Internets alle Prognosen bei weitem ubertroffen, die RIPE (Reseaux IP Europeens) Statistik zahlt mittlerweile weit uber 200 Mio., permanent ans Internet angeschlossene Hosts in ihrem Einzugsbereich, mit einer geschatzten Wachstumsrate von ca. 100% pro Jahr. Vor diesem Hintergrund ist davon auszugehen, dass die zur Adressierung zur Verfugung stehenden IP-Adressen zunehmend knapper werden. Da diese Entwicklung seit langerem absehbar ist, startete die IETF (Internet Engineering Task Force) bereits 1991 mit der Entwicklung eines IPv4 Nachfolgers. Aus mehreren Vorschlagen wurde 1994 IPv6 ausgewahlt, das neben dem weitaus grosseren Adressraum weitere Verbesserungen im Vergleich zu IPv4 bietet. In der vorliegenden Fallstudie wird davon ausgegangen, dass der Adressraum von IPv4 bereits in etwa 2 Jahren erschopft sein wird. Als CTO (Chief Technolo-gy Officer) eines ISPs (Internet Service Providers) soll nun eine Strategie fur die Umstellung von IPv4 auf IPv6 erstellt werden. Dabei ist zu berucksichtigen, dass Kunden des ISP fur noch ca. 4 Jahre eine IPV4-Anbindung mit fest zugeordneten Adressen benotigen und daruber hinaus Anbindungen zu weiteren ISPs unterhalten werden mussen, welche die IPv6 Migration erst in etwa drei Jahren abschliessen werden. Diese Anbindungen mussen fur die Ubergangszeit weiter unterhalten werden. Um die Technischen Grundlagen und Problemstellungen zu beleuchten, wird vor der konkreten Darstellung einer Migrationsstrategie erlautert, weshalb ein Umstieg von IPv4 auf IPv6 notwendig ist und wo die wesentlichen technischen Untersch"
