Bind 9.4.1 configuration needed

[Iñaki Martínez Díez]

Hi,

 I need a special (i think) bind 9.4.1 configuration, my requisites are:

 * NO local zones only queries
 * queries to Root servers
 * Only queries from a list of IPs and Networks
 * Very loaded because of lots of queries (about 500 servers querying
lots per second)
 * Cache only bind (how to delete/flush a cached zone??)

 I think this is all i need.

 Can anybody help me???


 Thank you in advance.
