Changed Features

noforward This option cannot be specified in Options statement in BIND 9.2.0. Instead forwarding can be suppressed by including an empty forwarders sub-statement as shown in the following example:

options {
    forwarders {192.249.249.1; };
        }
zone “hp.com” {
    type slave;
    masters { 192.249.249.4; };
    file “db.hp”;
    forwarders { };
}

This will suppress queries like “foo.india.hp.com” from being forwarded to nameservers at 192.249.249.1.

	NOTE: Forwarding to the nameservers available in the delegation information cannot be suppressed using an empty forwarders sub-statement.

alias-ip

This option is now no longer supported. Use the “listen-on” option of the “Options” statement to implement the alias-ip option.

auth-nxdomain yes/no

If this option is specified as yes, then the AA bit is always set on NX domain responses, even if the server is not actually authoritative. The default value for this option has been changed from “yes” to “no”.
