You're not alone.  It wasn't until I went to work for Rodney at Ultra a
few years ago until I realized how much I didn't know.  Then I began to
discover how much about DNS, both in terms of operational behavior and
protocol nuances weren't always documented or easily known until I
spent more time exploring and hanging out with the DNS cognoscenti.

There are at least a few areas of concern that you should consider.  At
the risk of come off a bit vain, beginning on slide 27 I've recently
been trying to highlight a few of them, which you might find useful to
review:

In some cases there are BCPs, but in many other cases it all depends on
your situation.  Asking the questions and reasoning about the answers is
a good approach to get to something decent.  I'd be interested in
co-authoring an IETF BCP on those sorts of things if I could get some
help.
