Heres the deal, about a month ago(I just remembered), I was at a clients site resolving some exchange server problems in a typical small business microsoft network. I was testing dns resolution and ran across the strangest thing. from my laptop (linux) I would run dig @4.2.2.2 dnsnamehere.com MX its my understanding that it is supposed to query only 4.2.2.2 for this answer. I got a reply of 192.168.1.11 the inside address for the mail server (i am in their network at this moment). However if I test from 4.2.2.2 (or any other dns server) from outside their network I get the correct outside address. the dns files do not have the inside address's in them so how could I be getting this internal address? it doesn't make any sense. Thanks. -- Entelin
