> Is it possible to blacklist some site?
A few ways work for me.
Create a zone and use file "/dev/null"; A lookup will return with status:
SERVFAIL.
Or create a dummy zone without the A records. A lookup will return with
status: NXDOMAIN.
Or for the zone use:
allow-query { none ; };
and lookups will return with status: REFUSED.
