What once seemed nearly impossible has turned into reality. The number of available Internet addresses is now nearly exhausted, due mostly to the explosion of commercial websites and entries from an expanding number of countries. This growing shortage has effectively put the Internet community--and some of its most brilliant engineers--on alert for the last decade. Their solution was to create IPv6, a new Internet standard which will ultimately replace the current and antiquated IPv4. As the new backbone of the Internet, this new protocol would fix the most difficult problems that the Internet faces today--scalability and management. And even though IPv6's implementation has met with some resistance over the past few years, all signs are now pointing to its gradual worldwide adoption in the very near future. Sooner or later, all network administrators will need to understand IPv6, and now is a good time to get started. IPv6 Network Administration offers administrators the complete inside info on IPv6. This book reveals the many benefits as well as the potential downsides of this next-generation protocol. It also shows readers exactly how to set up and administer an IPv6 network.A must-have for network administrators everywhere, IPv6 Network Administration delivers an even-handed approach to what will be the most fundamental change to the Internet since its inception. Some of the other IPv6 assets that are covered include: * routing * integrated auto-configuration * quality-of-services (QoS) * enhanced mobility * end-to-end security IPv6 Network Administration explains what works, what doesn't, and most of all, what's practical when considering upgrading networks from the current protocol to IPv6.
Über den Autor und weitere Mitwirkende
Niall Murphy has worked in the I.T. and Internet industries since 1995. His initial exposure to computers came with an Amstrad CPC 464 in the early 1980s, from which he never recovered. In college, Niall founded the UCD Internet Society which, at its height, gave Internet access to over two and a half thousand students who would not otherwise have had it. He also played way too much chess.
During the process of obtaining a degree in Computer Science and Mathematics, he held down a variety of programming, system and network administration and security-related jobs. After college, he went on to found his own consulting company, and participate in the start-up phase of a large number of companies and projects including Club Internet, Digifone On-Line, and Hutchison 3G. He used to run the root nameservers for Ireland, and is proud of having started five RIPE LIRs.
He has experience in networking of almost every kind (with the grateful exception of X.25) UNIX and Windows system administration, C systems programming, Perl, PHP, database creation and management, and Internet/IP services of all kinds, with specialities in database-backed web applications, wireless networking and next-generation networking.
As per the old adage, he thinks UNIX is the worst operating system there is, apart from all the others. He is a published poet, RFC co-author and O' Reilly co-author who does landscape photography for fun; you can see some of his work at South Bull Photography.
David Malone is a mathematician-cum-sysadmin. He is a researcher in the Hamilton Institute in Maynooth, Ireland, working on mathematical models of communications networks. Since 1994, he's also been a member of the sysadmin team of the School of Mathematics located in Trinity College Dublin, Ireland. There he helps to maintain a Unix-like service provided by FreeBSD and Linux machines. Naturally, they all speak IPv6.

Derzeit tritt ein Problem beim Filtern der Rezensionen auf. Bitte versuchen Sie es später noch einmal.
Es gibt jedoch keine wirkliche Anbieter die es ihren Kunden ermöglichen native mit IPv6 auf das Internet zuzugreifen. Trotzdem sollte man als Netzwerktechniker sich mit dem Thema jetzt schon auskennen, um eventuelle Sicherheitsprobleme später rechtzeitig erkennen zu können. Hier setzt das Buch sehr erfolgreich ein. Es erklärt deutlich die Vorteile von IPv6 und die nachteile von IPv4.
In späteren Kapiteln wird an sehr vielen Beispielen die Konfiguration von IPv6 gezeigt, auch abseits von dem Mainstreambetriebssystem Windows.
Ein gutes Buch für alle die sich mit dem Thema auseinander setzen wollen.

Well worth the money in how much time it will save you.
Not much platform-specific stuff, but there is no way they could have covered all the platforms. I am working with VMS, AIX, Tru64 and HPUX, and you really can't expect every platform to be covered. Consult local documentation for platform specifics.
The preface, a less than useful part of many books, offers an interesting history of IPv6 development. Rather than assume IPv4 is worthless, ch 1 and 2 debate IPv4's merits; ch 1 is anti-IPv4 and ch 2 is pro-IPv4. In ch 3 we learn IPv6 details, and here the authors' writing style and judgement shines. They avoid describing every detail of IPv6, and instead summarize or present just the important parts of the protocol. This technique could have earned the book the title "Practical IPv6".
Another smart choice made by the authors involves relating IPv6 concepts in IPv4 terms, where possible and appropriate. For example, ch 3 shows how neighbor solicitation fulfills a role similar to ARP. It will be many years before any student of networking will have to ignore learning IPv4, so I appreciate authors who speak in familiar terms.
Beginning in ch 5 and elsewhere, the authors make a third excellent decision. Rather than just present a Linux command reference and a Windows command reference, they present syntax for many operating systems and networking devices. This must have taken a decent amount of research, but such level of detail makes the work accessible to a wide audience. I found the use of FreeBSD in repeated examples to be particularly appealing.
The authors are not shy about saying what works and what doesn't when IPv6 is involved. In ch 7 they present some novel ways to work around certain issues, e.g., using netcat6 for port forwarding IPv6 traffic. They even show programming examples and outline new aspects of the sockets API to handle IPv6 addressing in ch 8.
Finally, IPv6 Network Administration presents workable ways for admins to give IPv6 a try, such as 6to4 and other tunnel methods. Almost anyone with a public IP address should be able to experiment with IPv6 thanks to the book's directions. Given that I operate multiple IPv6-capable systems in my lab, I was able to test some of the book's commands using link-local addressing (described in the text).
In brief, this is a must-have book for all network administrators. Even if you never intend to deploy IPv6, you should understand it as a professional technician. As a personal observation, I see many opportunities for intruders to exploit misconfigurations, poor coding, and various complexities in IPv6 (such as the huge variety of addresses assigned to single machines). IPv6 Network Administration will help get an IPv6 network running, at least to the point where administrators can begin becoming familiar with this new network protocol.
Both of these books are good. but those interested in
IPv6 for OpenBSD will probably find IPv6 Essentials more
useful since this book does not mention OpenBSD at all, whereas the Essentials book
describes details of enabling optional ip6 features in OpenBSD (OpenBSD comes with
both ip4 and ip6 enabled by default) and even mentions OpenBSD
in the index.
Proofreading at OReilly is slipping. I have encountered
grammatical errors in the text that make me wonder if
English is the native language of the proofreader(s).
Also, note that O'Reilly appears to have severed
all email links to the rest of the world. The email addresses given in OReilly books no longer work,
(I tried to send this info to O'Reilly using the email address given in the book but the email bounced.)
What I got instead was sort of a relaxed technical rambling from a couple of guys that clearly know IPv6 but don't know the next thing about how to teach others about it. (Think of two super-qualified IPv6 experts musing aloud about IPv6 while sitting in comfy leather chairs, wearing cardigans with elbow patches, beside a crackling fireplace, in a mountain cabin, in snowy weather.) I suffered through two whole chapters of the obligatory pros and cons of IPv4 at the beginning only to see IPv6's workings disposed off in a single chapter. Albeit with promises that we would "..get down to the juicy details later in Chapters 4 and 6." No such luck I'm afraid.
The book also suffers from a particularly acute case of let-me-tell-why-this-is-great that most engineers suffer from when asked to explain what they've come up with. Here's a quote from chapter 3's second paragraph to illustrate the point:
"When we talk about networking protocols in general it's important to understand the difference between specification and implementation."
Ummm, yes, if you are implementing the blasted thing. Not so much if you are a technical user of it. I knew I was in trouble after this point in the book.
So I excused myself, left the mountain cabin and took the cable car back into town. I hightailed it to the nearest bookstore and bought myself "Understanding IPv6, Second Edition" by Joseph Davies from Microsoft Press. Now here is a book that disposes off the obligatory IPv4 pros and cons in a couple of pages and gets to the meat of the matter in no time, i.e the actual workings of IPv6, its fields, their meanings and how they are used. As an added bonus, this book also does a great job of covering IPv6 transition options.
Buy "Understanding IPv6, Second Edition" and save your money. Or better, send me a postage paid book envelope and I'll send you my copy of "IPv6 Network Administration".
