Just upgraded bind and see that it reccomends adding some lines to
named.conf to avoid the A wildcard

 *      zone com IN { type delegation-only; };
 *      zone net IN { type delegation-only; };

I have named.conf set to forward to the upstream DNS only (ISP,
University DNS etc): e.g.,
 forwarders {
        //      123.123.123.123;
        //      123.123.123.123;
                nnn.nnn.nnn.nnn;
        };

Is this necessary in my configuration, if not, when should the above be
used.  I use bind as a pure caching DNS at some sites, and with some
local zones added at others.
