Methinks you didn't read what I wrote.  I tested using dig and nslookup,
I already knew that they tell which server answered, they told me that
the same one kept answering.  Nor, noticed where I mentioned the timing
of results, in an earlier message.

So, either those tools behave differently than other things doing name
lookups on the system, or the system ignores the directive to
round-robin the lookups.

Which means doing a test with another tool, and looking at the logs,
which I haven't done yet as I've been otherwise occupied.
