For a technology so crucial, DNS has been sadly underdocumented. Ditto for BIND, long the most popular implementation of the DNS specifications. Web administrators hand down their secrets like treasured family heirlooms, or they reinvent the wheel over and over again, decade after decade. Or they get DNS and BIND. If ever a book filled a need, it’s this one.
Which brings us to the new Fifth Edition. You might figure DNS and BIND were thoroughly mature by now. What more can be said about using them effectively? Plenty.
First, this edition’s been updated to reflect the new 9.3.2 and 8.4.7 versions of BIND. Don’t worry if your distribution hasn’t upgraded yet -- the coverage you need is still here.
So is all-new coverage of the Sender Policy Framework (SPF) for identifying and rejecting forged email. So are new discussions of advanced features ranging from signed dynamic updates to IPv6 forward and reverse mapping. The book’s security chapter has been updated with coverage of transaction signatures; expanded discussions of firewalls and securing nameservers; and the latest on DNS Security Extensions. There’s revised coverage of making BIND and Active Directory coexist. You’ll even learn how to map E.164 phone numbers to URIs.
As in previous editions, DNS and Bind is organized to follow your zone’s evolution, and your own growing expertise as a DNS administrator. You’ll learn just enough theory, decide whether to set up your own zones, then walk through doing so, step-by-step. The authors cover zone maintenance, configuring hosts to use nameservers, planning for growth, subdomains, and much more.
There’s a full section on troubleshooting. And the book’s replete with coverage of tools, including many of the authors’ own Perl programs. Indispensable then; indispensable now. Bill Camarda, from the July 2006 Read Only
