Dear people, I know the best way is to make in-addr.arpa local zones in my BIND.
But also I think the BLACKHOLE SERVERS can be used, because they were created for this reason.: respond to RFC 1918 networks queries. So why the BLACKHOLE servers don't respond anymore ? Just one time I could get a responde from them.
