9. How to become a bigger time DNS admin.

Documentation and tools.

Real Documentation exists. Online and in print. The reading of several of these is required to make the step from small time DNS admin to a big time one. In print the standard book is DNS and BIND by C. Liu and P. Albitz from O'Reilly & Associates, Sebastopol, CA, ISBN 0-937175-82-X. I read this, it's excellent. There is also a section in on DNS in TCP/IP Network Administration, by Craig Hunt from O'Reilly..., ISBN 0-937175-82-X. Another must for Good DNS administration (or good anything for that matter) is Zen and the Art of Motorcycle Maintenance by Robert M. Prisig :-) Available as ISBN 0688052304 and others.

Online you will find stuff on,; A FAQ, a reference manual (BOG; Bind Operations Guide) as well as papers and protocol definitions and DNS hacks (these, and most, if not all, of the rfcs mentioned below, are also contained in the bind distribution). I have not read most of these, but then I'm not a big-time DNS admin either. Arnt Gulbrandsen on the other hand has read BOG and he's ecstatic about it :-). The newsgroup is about DNS. In addition there are a number of RFCs about DNS, the most important are probably these:
