Recursion issue

Maybe my understanding of how bind works is faulty.
I thought bind would do the leg work to get an IP.
Especially when it is authoritative for CNAME domain.
Even a dig on mercury gives the same 'no IP' result.
Sorry for the bother.

OK, bad choice of words on my part. I did not mean to say that you should not set any configuration options to disable recursion, because as you said, it is on by default (but restricted, by default, to localnets and localhost). What I meant was that there is no reason to permit recursive queries to your authoritative servers. Therefore, I would recommend turning it off using 'recursion no;' in your options or view statement.
