Comprehensive guide to configuration and administration of DNS servers

Covers DNS Extensions, delegation, and registration

Description

The Domain Name System is one of the foundations of the internet. It is the system that allows the translation of human-readable domain names into machines-readable IP addresses and the reverse translation of IP addresses into domain names. This book describes the basic DNS protocol and its extensions; DNS delegation and registration, including for reverse domains; using DNS servers in networks that are not connected to the internet; and using DNS servers on firewall machines. Many detailed examples are used throughout the book to show perform various configuration and administration tasks.

What you will learn

This book covers all the basic as well as advanced uses of DNS

Chapter 1 introduces basic DNS concepts, such as domains and subdomains, domain naming syntax, reverse domains, zones, queries, resolvers, name servers, forwarder servers.

Geoff S. Jul 20, 2006

According to the title page of this book, it is an English translationof a Czech book (ISBN 80-722-6675-6) published in 2003, apparently froma manuscript completed in 2001 (based on the dates used in theexamples).The content has not been appreciably updated, if it's been updated atall. For example, in Section 3.5.1 and 3.5.2, the book discusses AAAAand A6 resource records, noting "The use of the AAAA record will notprevail in the future, though". However, the IETF moved the A6 recordto EXPERIMENTAL status in 2001 (!), effectively deprecating it in favorof AAAA. In fact, the book is dangerously out-of-date, as it has anextensive treatment of BIND 4 without anywhere noting that theISC -- the maintainer of BIND -- deprecated BIND 4 in 1997. (BIND 4 isnow widely regarded as unsafe for use in a production environment.)The woefully dated content isn't the only problem. The translationfrom Czech is sloppy, with many typographical errors and awkwardsentences. There are many artifacts from what was presumably initiallya machine translation. There are also quite a few minor inaccuracies,and negligible coverage of security issues (other than a section on anobsoleted version DNSSEC).In short, I cannot warn strongly enough against this book. It'sinadequate, even as a primer. I would recommend one of theseimmeasurably better books on DNS for anyone at any levelseeking to learn more about DNS:- Pro DNS and BIND, by Ron Aitchison (ISBN 1590594940)- DNS and BIND (5th Edition), by Cricket Liu and Paul Albitz (ISBN 0596100574)

John Dickinson Jul 17, 2006

When I got this book I flicked to the section on DNSSEC in order to see how up to date this book is. I was horrified to see that the whole section is based on RFC 2535. This is now obsolete and has been replaced by RFC's 4033, 4034 and 4035. These new RFC's had been out for a year by the time this book was published.
