If a client sends a recursive query to the BIND instance, and that instance needs to fetch the answer from one or more other upstream sources, then my understanding is that the "resolver-query-timeout" global option (see the BIND docs) controls the timeout for each one of those upstream transactions. Default value is 10 seconds.

Does that answer your question?

I am looking at some scripts that use IO::Socket::INET and IO::Select for testing BIND.

UDP sockets are created use use IO::Socket::INET and sockets are polled via IO::Select at 6-second interval.

my  $sock = IO::Socket::INET->new(
            PeerHost => $server,
            PeerPort => $port,
            Proto    => $protocol,
            Blocking => 0,

I'd like to know what the timeout is for the queries.

Thanks,
Shawn
