    The above are trying to use your nameserver for domains you do not host. It's safe to ignore this as it means your configuration is doing what it should, and blocking them from doing lookups.

    So I could use the logging {} in named.conf to filter and not log them?

    it doesn't seem to be working, here is what my named.conf looks like:
    Code:
    logging
    {
    /*      If you want to enable debugging, eg. using the 'rndc trace' command,
     *      named will try to write the 'named.run' file in the $directory (/var/named).
     *      By default, SELinux policy does not allow named to modify the /var/named directory,
     *      so put the default debug log file in data/ :
     */
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
    
        channel queries-log {
                    file "/var/named/queries.log" versions 10 size 250m;
                    severity info;
                    print-time yes;
                    print-severity yes;
            };
    
            category lame-servers { null; };
    //      category queries { queries-log; };
    };
