DNS and BIND discusses 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 write in the preface, if you're using the Internet, you're already using DNS -- even if you don't know it.The third edition covers BIND 4.9, on which most commercial products are currently based, and BIND 8, which implements many important new features and will be the basis for the next generation of commercial name servers. It also covers topics like DNS security (greatly improved with BIND 8.1), asynchronous notification of changes to a zone, dynamic updates, and programming with Perl's Net::DNS module.Whether you're an administrator involved with DNS on daily basis, or a user who wants to be more informed about the Internet and how it works, you'll find that this book is essential reading.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, etc.
Mapping one name to several servers for load sharing
Troubleshooting: using nslookup, reading debugging output, common problems
DNS programming, using the resolver library and Perl's Net::DNS module
Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The insects featured on the cover of DNS and BIND are grasshoppers. Grasshoppers are found all over the globe. Of over 5000 species, 100 different grasshopper species are found in North America. Grasshoppers are greenish-brown, and range in length from a half inch to four inches, with wingspans of up to six inches. Their bodies are divided into three sections: the head, thorax, and abdomen, with three pairs of legs and two pairs of wings.Male grasshoppers use their hind legs and forewings to produce a "chirping" sound. Their hind legs have a ridge of small pegs that are rubbed across a hardened vein in the forewing, causing an audible vibration much like a bow being drawn across a string.Grasshoppers are major crop pests, particularly when they collect in swarms. A single grasshopper can consume 30mg of food a day. In collections of 50 or more grasshoppers per square yard--a density often reached during grasshopper outbreaks--grasshoppers consume as much as a cow would per acre. In addition to consuming foliage, grasshoppers damage plants by attacking them at vulnerable points and causing the stems to break off. Ellie Fountain Maden was the production editor and copy editor forDNS and BIND, 3rd edition; Sheryl Avruch was the production manager. Melanie Wang performed the proofread, and Madeleine Newell and Nicole Gipson Arigo provided quality control. The content was formatted from SGML into FrameMaker 5.5 with Jade, using a DSSSL conversion stylewheet written by Chris Maden. The inside layout uses ITC Garamond Light and ITC Garamond Book fonts, and was designed by Nancy Priest and Edie Freedman. Additional tools support was provided by Mike Sierra and Don Ohl. The figures were created in Adobe Photoshop 5 and Macromedia Freehand 7 by Robert Romano. Seth Maislin wrote the index. This colophon was written by Clairemarie Fisher O'Leary.Edie Freedman designed the cover of this book, using a 19th-century engraving from the Dover Pictorial Archive. The cover layout was produced with Quark XPress 3.3 using the ITC Garamond font. Whenever possible, our books use Rep-Kover (tm), a durable and flexible lay-flat binding. If the page count exceeds Rep-Kover's limit, perfect binding is used.
This is an excellent, educational, USEABLE book. I recently got a job at an ISP,
and it seems like 75% of my work revolves around DNS. I really need to learn and know DNS and BIND. DNS problems are often subtle and difficult to track down, and I am using this book on a daily basis to help me learn my job. A big "Thank you" to Paul Albitz and Cricket Liu.
