Since the test is built into bbtest-net, and we can't duplicate the
problem, and if the person with the issue is sure that a dig on the
server name does work, maybe it's an issue with either the build of
bbtest-net, or with your bb-services file.
Is there any chance you have added a section [dns] to your
etc/bb-services file? I can simulate your problem by adding one (OK,
but no DNS lookup output). If so, please remove it.
