New Features

Chapter 1 25

Following are the periodic task intervals options:

cleaning-interval number;

The cleaning-interval option speciﬁes the time interval after which

the server removes the expired resource records from the cache. The

default value is 60 minutes. If cleaning-interval is set to 0, periodic

cleaning does not occur.

interface-interval number;

The interface-interval option speciﬁes the time interval for which

the server scans the network interface list. The default value is 60

minutes. If this option is set to 0, interface scanning occurs only when

the conﬁguration ﬁle is loaded. After the scan, listeners are started on

any new interface (provided they are allowed by the listen-on

conﬁguration). Listeners on interfaces that have expired are removed.

statistics-interval number;

The statistics-interval option speciﬁes the time interval for which

name server statistics are logged. The default value is 60. If this option is

set to 0, statistics are not logged.

sortlist { ip_addr; ... }

You can use the sortlist entry to indicate the preference of networks,

unlisted networks. During a query, address sorting occurs only when the

host and server are on the same network. The best address is placed ﬁrst

in the response. The address preference order is local network addresses,

then addresses on the sort list, then other addresses.

Following is an example for sortlist:

sortlist{

10.0.0.0;

26.0.0.0;

};

The server Statement

The server statement deﬁnes the remote name server characteristics.

For example, if a name server is giving incorrect data, you can mark the

name server to prevent further queries to it.

The server supports two zone transfer methods that can be deﬁned

within the transfer-format phrase in the server statement.
