thanks mark,

It appears my case may be a programming error from the server admin. But this brings up the case of views.

on my external dns server i should add an empty zone file ? what does that send back to the offending request?

zone "10.IN-ADDR.ARPA" {
        type master;
        file "empty";

is there a way i can redirect him back to the Internal dns server for 1918 requests,... ( and i think the answer is ,.. let the internal answer the initial request so it never comes up to the outside).
