I used the 3rd edition as reference to fix a resolver problem in HP-UX. This involved bad nameserver maintenance from the parent. Having read half of the 3rd edition, and now nearly all of the 4th, I must say Cricket and Paul have truly improved on a great effort. This book gives everything you will need to manage DNS/BIND for version 4, 8 and 9. Anything more must be obtained from RFCs, of which there are numerous references. Thanks for the enjoyable reading.
