<p class="MsoNormal">Actually, I was wondering why those answers are NODATA rather than NXDOMAIN since presumably there aren't other record types at the name I queried. It looks like this is because this zone is in the controlled interruption mode (it has a
wildcard at the apex for A, MX, etc).<o:p></o:p></p>
