Hi,

What should I (or should be) do in order to prevent this kind of events appearing in my log files:

Aug 30 04:02:18 europe named[1240]: lame server resolving '198.196.210.64.in-addr.arpa' (in '196.210.64.in-addr.arpa'?): 209.1.222.247#53
Aug 30 04:02:18 europe named[1240]: lame server resolving '198.196.210.64.in-addr.arpa' (in '196.210.64.in-addr.arpa'?): 209.1.222.246#53

and the list is quite long and containing the same line.

Thanks for any input.

In your named.conf, add

category "lame-servers" { "null"; };

inside the logging section... assuming you are running bind 9.x.
