First of all, why do you think hints would be excluded from "view" 
differentiation? Secondly, one of the views in the configuration 
described doesn't even need hints, because it's master for the root 
zone. What Barry describes should work just fine. In fact, if an 
organization had only 1 server and 1 IP address to use for internal and 
external DNS, and for whatever reason insisted on having an 
internal-root architecture, this is what they'd *have* to do. While 
questionable from a security standpoint, I'm sure ISC/Nominum has 
contemplated and probably tested such a minimalistic implementation of
