allow-recursion
Similar to allow-query, this option applies to recursive queries. By default, all hosts are allowed
to perform recursive queries on the nameserver.
blackhole
Specifies which hosts are not allowed to query the server.
directory
Specifies the named working directory if different from the default value, /var/named/.
forwarders
Specifies a list of valid IP addresses for nameservers where requests should be forwarded for
resolution.
forward
Specifies the forwarding behavior of a forwarders directive.
The following options are accepted:
• first — Specifies that the nameservers listed in the forwarders directive be queried before
named attempts to resolve the name itself.
• only — Specifies that named does not attempt name resolution itself in the event that queries
to nameservers specified in the forwarders directive fail.
listen-on
Specifies the network interface on which named listens for queries. By default, all interfaces are
used.
Using this directive on a DNS server which also acts a gateway, BIND can be configured to only
answer queries that originate from one of the networks.
The following is an example of a listen-on directive:
options { listen-on { 10.0.1.1; }; };
In this example, only requests that arrive from the network interface serving the private network
(10.0.1.1) are accepted.
notify
Controls whether named notifies the slave servers when a zone is updated. It accepts the
following options:
• yes — Notifies slave servers.
• no — Does not notify slave servers.
• explicit — Only notifies slave servers specified in an also-notify list within a zone
statement.
pid-file
Specifies the location of the process ID file created by named.
