Another solution could be to make one of the names a CNAME pointing to
the other name.
Just use one generic name for both services. rather than the two
Although in all honesty, I see nothing wrong with a lookup returning two
answers (in a single response packet) for the one reverse query. BIND
certainly is not confused. I guess it confuses people?
I've written various scripts to do various DNS checks and have always
made (programmed for) this assumption - that there may be more than one
answer and there may also be CNAMEs involved. If other software is
confused - then perhaps it is badly written?
Some people do though, I believe, go overboard...
