I do this in named.conf...
zone "atdmt.com" {
type master;
file "db.empty_zone";
};
zone "doubleclick.net" {
type master;
file "db.empty_zone";
};
then, I have a single file called db.emtpy_zone
$TTL 36000
@ IN SOA my.dns.server. email.address.i.use.in.zones. (
1 ; serial
36000 ; refresh
18000 ; retry
1209600 ; expire
36000 ; minimum
)
NS my.dns.server.
* A 1.1.1.1 ;
NOTE: The 1.1.1.1 A record is optional.
If you use this, you should point it to your
own web server.
