/var/named/db.blackhole (was: HAMMER = BAN ! :-) RE: Tcp port 7

[Roger Marquis <marquis () roble com>]

This is easily accomplished by adding doubleclick.net to your local DNS
maps.  That way users can decide by their choice of nameserver.  Works
great, less traffic, and best of all: nobody seems to mind.

#grep doubleclick /etc/named.conf
zone "doubleclick.net" { type master; file "db.blackhole"; };

#cat /var/named/db.blackhole
@ IN SOA localhost. hostmaster.localhost. (
         98051511 10800 1800 604800 86400 )
  IN     NS blackhole.isi.edu.
