Thanks you for your time Kenneth and Stefan. I didn't include the 
important part that I am asking about the recursor only. I will 
look at lua. We may look at iptables also.


There seems to be a large potential for a DoS if upstream the TTL 
gets changed extremely low. Making them low would make the cache 
expire and there would need to be another lookup.

Stefan the recursor.conf has places "Don't change". Does the tree 
make a sound while no one around? Or does a config that doesn't 
change need to be a config? Or does the code need to be 
removed/redone?
