Most external domains do not resolve (missing root servers?)

[Kevin Darcy]

Do you only trust your own subnet? Or, perhaps there are other adjacent 
subnets that may be needing to use your nameserver for resolving 
Internet names (?)

The identity/size of the "allow-recursion" range needs to be informed by 
your overall Internet-facing network topology. Talk to your network 
architect if necessary to get the appropriate values.

                                                                         
                     - Kevin
