amount of memory used by the server, but it can be used to raise an operating system
data size limit that is too small by default. If you wish to limit the amount of memory
used by the server, use the max-cache-size
and recursive-clients
options
instead; see the Server Resource Limit Options section.
files The maximum number of files the server may have open concurrently. The default is
unlimited.
stacksize The maximum amount of stack memory the server may use. The default is
default.
Periodic Task Interval Options
cleaning-interval
The server will remove expired resource records from the cache every
cleaning-
interval minutes. The default is 60 minutes. The maximum value is 28 days (40320
minutes). If set to 0, no periodic cleaning will occur.
heartbeat-interval
The server will perform zone maintenance tasks for all zones marked as
dialup when-
ever this interval expires. The default is 60 minutes. The maximum value is 28 days
(40320 minutes). Reasonable values are up to 1 day (1440 minutes). If set to 0, no zone
maintenance for these zones will occur.
interface-interval
The server will scan the network interface list every interface-interval
minutes.
The default is 60 minutes. The maximum value is 28 days (40320 minutes). If set to 0,
interface scanning will only occur when the configuration file is loaded. After the scan,
listeners will be started on any new interfaces (provided they are allowed by the
listen-on configuration). Listeners on interfaces that have gone away will be cleaned
up.
Query Address Options
If the server is unable to answer a question, it will query other name servers.
query-source
Specifies the address and port used for such queries.
query-source-v6
Specifies the address and port used for queries sent over IPv6.
If address is
* or is omitted, a wildcard IP address (INADDR_ANY) is used. If port is
* or is omitted, a
random unprivileged port will be used. The default address and port are:
query-source address * port * ;
query-source-v6 address * port * ;
Note: The address specified in the
query-source option is used for both UDP and TCP queries, but
the port applies only to UDP queries. TCP queries always use a random unprivileged port.
RRset Ordering Option
When multiple records are returned in an answer, it may be useful to configure the order of the records
placed into the response.
The rrset-order option permits the configuration of the ordering of the records in a multiple record
response.
order_spec is defined as:
[ class class_name ][type type_name ][name "domain_name" ]
order ordering
If no
class is specified, the default is ANY.Ifnotype is specified, the default is ANY.Ifnoname
is specified, the default is *.
The values for ordering are:
fixed Records are returned in the order they are defined in the zone file.
random Records are returned in some random order.
cyclic Records are returned in a round-robin order.
