You could turn on debugging, to be sure. Or, you could just dump your cache and
see what's in it or not, expired or not. Anything lacking a valid, unexpired
cache entry is going to require communication with the outside to resolve,
which is going to introduce some measure of delay.
not sure hwat you mean but likely

In the second case, the answer was cached and so your resolver didn't have to

Hi all,
I'm struggling about "query time" :-/
Using bind 9.9.5, I configurated it as caching proxy:
dig yahoo.it @192.168.1.212
[...]
96msec
second time:
dig yahoo.it @192.168.1.212
[...]
1msec
seems it works but: if I waiting (ie 5 minutes) and I re-run same
command, "query time" was increa

running BIND, version 9.8.1 on the master for the zone, and version 9.9.5
on the slave.
The forwarding requests are coming from a pair of Microsoft DNS servers,
running Server 2012.

"Internet primary dns", are you referring to the .i
Huh?
are you sure you want to replicate whole server?
