First thing you should do is not to filter out or explain the dig<br>
commands you use and their results, but instead to just copy-paste the<br>
command and its output. Here, for instance, none of what you provide<br>
allows checking how the request was sent exactly, and what principal<br>
and additional info was returned.<br>
