DNS and BIND tells you everything you need to work with 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 even listing phone numbers with the new ENUM standard. This book brings you up-to-date with the latest changes in this crucial service.
The fifth edition covers BIND 9.3.2, the most recent release of the BIND 9 series, as well as BIND 8.4.7. BIND 9.3.2 contains further improvements in security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework).
Whether you're an administrator involved with DNS on a 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.

* Using MX records to route mail
* Configuring hosts to use DNS name servers

* Mapping one name to several servers for load sharing

Cricket Liu matriculated at the University of California's Berkeley campus, that great bastion of free speech, unencumbered Unix, and cheap pizza. He joined Hewlett-Packard after graduation and worked for HP for nine years. Cricket began managing the hp.com zone after the Loma Prieta earthquake forcibly transferred the zone's management from HP Labs to HP's Corporate Offices (by cracking a sprinkler main and flooding Labs' computer room). Cricket was firstname.lastname@example.org for over three years, and then joined HP's Professional Services Organization to cofound HP's Internet Consulting Program. Cricket left HP in 1997 to form Acme Byte & Wire, a DNS consulting and training company, with his friend (and now co-author) Matt Larson. Network Solutions acquired Acme in June 2000, and later the same day merged with VeriSign. Cricket worked for a year as Director of DNS Product Management for VeriSign Global Registry Services. Cricket joined Men & Mice, an Icelandic company specializing in DNS software and services, in September, 2001. He is currently their Vice President, Research & Development. Cricket, his wife, Paige, and their son, Walt, live in Colorado with two Siberian Huskies, Annie and Dakota. On warm weekend afternoons, you'll probably find them on the flying trapeze or wakeboarding behind Betty Blue.
