OK. Wrong term. So my question is : what is the default behaviour of BIND
when you have multiple RRs with the same label, class and type (but not
data) with Bind 9.2.3+ and Bind 9.3.x (Remember I have asked questions about
Round Robin) ? ...

Sorry, but I'm getting confused with the behaviour of several Bind versions
(I have tested) and I would like to have an answer from a Bind expert. Also,
since I didn't find these informations in documentation and in archives, it
would be a good idea to leave a trace for such questions.

Thanks anyway for your answer.

Sincerely yours,
Mathieu MILLET.
