Greetings all, Please forgive me if this question is a bit off-topic for this list. I can be sure if it is or isn't until I get the answer.
My question is rather a simple one. Given some FQDN `D' and given some DNS record type 'T' (e.g. either A or AAAA or perhaps even PTR) does there exist some open source command line tool that can tell me the names of the DNS servers to which the final authority for answering a query about the tuple (D, IN, T) is delegated? I know that I can get this information by using "dig +trace", but that seems to be rather slow to me (wall clock time), and I want to be doing this a lot. Also, of course, "dig +trace" puts out quite lot of information that is really of no use and no interest to me. I really just want the names of the final set of nameservers that should, if they are up and running, be the ones that will ultimately answer the query. So, does anyone know of an open source command line tool that can do just that, preferably quickly?
