Pro DNS and BIND

in general I would give 4.5 if it possible. 5 stars is too much unfortunately. Book has pleasant layout and general nice flow. Quite a lot of book is taken for references. You will find easily all important topics of DNS, but DNS and BIND O'Reilly book is much more in depth. Question is: do you need it? If you looking for massive DNS system, then maybe yes, but for average DNS administration it's not necessary. Book is easy for reading, apart some places where author forget a little his nice style for less smooth one. If you are looking for kindle edition: I have not massive experience with kindle format.. but why all tables with commands params are scanned? It's not scalable font, hard to read. Everything else: brilliant. I may recommended as nice refresh even if you know DNS pretty well. After couple of years resolving issues with DNS I still found some valuable tips here.
