DNS and BIND Summary

DNS and BIND by Paul Albitz

"DNS and BIND" is about one of the Internet's fundamental building blocks: the distributed host information database that's responsible for translating names into addresses, routing mail to its proper destination, and many other services. As the authors say in the preface, if you're using the Internet, you're already using DNS - even if you don't know it. This edition covers the 9.1.0 and 8.2.3 versions of BIND along with the older 4.9 version. There's also more extensive coverage of NOTIFY, IPv6 forward and reverse mapping, transaction signatures, and the new DNS Security Extensions; and a new section on accommodating Windows 2000 clients, servers and Domain Controllers. Whether you're an administrator involved daily with DNS or a user who wants to be more informed about the Internet and how it works, the book should be of interest. Topics include: what DNS does, how it works, and when you need to use it; how to find your own place in the Internet's name space; setting up name servers; using MX records to route mail; configuring hosts to use DNS name servers; subdividing domains (parenting); securing your name server: restricting who can query your server, preventing unauthorized zone transfers, avoiding bogus name servers, and so on; mapping one name to several servers for load sharing; troubleshooting: using nslookup, reading debugging output, common problems; and DNS programming, using the resolver library and Perl's Net::DNS module.

DNS and BIND Reviews

'Now into its fourth edition, updated to cover BIND 9, the O'Reilly textbook has already attained classic status. DNS and BIND can be found on the shelf, or more likely open on the desk, of most clued-up system administrators... Don't expect a fun read ... the subject matter is a little dry for that ... but if you like your Unix and want to truly understand how DNS works in general and in practice within your enterprise, this is the book to buy.' - Davey Winder, PC PRO, September 'This book has been the bible for DNS administration since 1992. .. I can't fault this new edition of the book. The first edition serve me well when I was setting up my first DNS server. The book still achieves what it sets out to do, and explains DNS and BIND. This has got more complicated (sorry, feature rich!) over the years, but this book still explains it in clear terms. O'Reilly rightly made their name through publishing titles like this.' - Joel Smith, new@UK, December 2001 'This book is as useful now as it was back in the mid 90's. Buy it if you have to do any more than be a simple user of DNS. As a measure of how times change, the appendices no longer show you how to compile and install BIND on a Sun operating system, it is now shown with Linux.' - Raza Rizvi, new@UK, December 2001

About Paul Albitz

Paul Albitz is a software engineer at HewlettPackard. Paul earned a bachelor of science degree from the University of Wisconsin, LaCrosse, and a master of science degree from Purdue University. Paul worked on BIND for the HPUX 7.0 and 8.0 releases. During this time he developed the tools used to run the domain. Since then Paul has worked on networking HP's DesignJet plotter and on the fax subsystem of HP's OfficeJet multifunction peripheral. Before joining HP, Paul was a system administrator in the CS Department of Purdue University. As system administrator, Paul ran versions of BIND before BIND's initial release with 4.3 BSD. Paul and his wife Katherine live in San Diego, CA. Cricket Liu matriculated at the University of California's Berkeley campus, that great bastion of free speech, unencumbered Unix and cheap pizza. He went to work for HewlettPackard after graduation and stayed at HP for nine years. Cricket began managing the zone after the Loma Prieta earthquake forcibly moved the zone's management from HP Labs to HP's Corporate Offices. He was for over three years, and then joined HP's Professional Services Organization to found HP's Internet consulting program. Cricket, his wife, Paige, and their son, Walt, live in Colorado with two Siberian Huskies, Annie and Dakota. On warm weekends, you'll probably find them on the flying trapeze.
