type slave;
masters { 192.249.249.4; };
file "db.hp";
forwarders { };
}
This will supress 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 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".
Compatibility with Previous Versions of BIND
This section provides the BIND compatibility information.
BIND 4.9.7 Compatibility
This section discusses the BIND 9.2.0-BIND 4.9.7 compatibility.
• BIND 9.2.0 uses a system assigned port for the UDP queries it makes rather than port 53 that
BIND 4.9.7 uses. This may conflict with some firewalls. To specify a port, edit the
/etc/named.conf file as follows:
query-source address * port 53;
nl
transfer-source * port 53
nl
notify-source * port 53;
• BIND 9.2.0 no longer uses the minimum field to specify the TTL of records without a explicit
TTL.
Use the $TTL directive to specify a default TTL before the first record without an explicit TTL.
The hosts_to_named script will create TTL value in the db files.
• BIND 9.2.0 does not support multiple CNAMEs with the same owner name. For example:
www.example.com. CNAME host1.example.com
www.example.com. CNAME host2.example.com.
In the above example, multiple records with the same owner name "www.example.com" are
not supported.
The named-checkzone program can be used to check the correctness of the database files.
• BIND 9.2.0 does not support "CNAMEs with other data" with the same owner name, ignoring
the DNSSEC records (SIG, NXT, KEY) that BIND 4.9.7 did not support. For example:
www.example.com. CNAME host1.example.com.
www.example.com. MX 10 host2.example.com.
