Chapter 1 15
This option is used to specify a list of addresses from which the
server will not accept queries or and does not use them to resolve a
query. Default is none. The syntax of blackhole option in the
“options” statement in the /etc/named.conf file is as shown below:
[ blackhole {address_match_list {; ]
• coresize
This option is used to specify the maximum size of a core dump.
Default is default. The syntax of coresize option in the “Options”
statement in the /etc/named.conf file is as shown below:
[ coresize size_spec ; ]
• sortlist
The sortlist statement takes an address_match_list and
interprets it. Each top level statement in sortlist must be an
explicit address_match_list with one or two elements. The first
element, which may be an IP address, IP prefix, acl name or a
nested address_match_list is checked against the source address of
the query until a match is found.
Once the source address of the query has been matched, if the top
level statement contains only one element, the actual element that
matched the source address is used to select the address in the
response to move to the beginning of the response. Each top level
statement element is assigned a distance and the address in the
response with the minimum distance is moved to the beginning of
the response.
A sample sortlist statement usage in the Options statement in
the /etc/named.conf file is as shown below:
[ sortlist { address_match_list }];
NOTE Refer to the named.conf(4) man page for more information on the
usage of sortlist statement.
• max-cache-size
max-cache-size is used to specify the maximum amount of memory
to use for the server’s cache, in bytes. When the amount of data in the
cache reaches this limit, the server will cause records to expire
