Для чего нужен сервер или как сделать сервер своими руками (mini Server)

Оператор options определяет глобальные параметры для BIND и протокола DNS. Синтаксис BIND 8:

options {
[ version string; ]
[ directory pathname; ]
[ named-xfer pathname; ]
[ dump-file pathname; ]
[ memstatistics-file pathname; ]
[ pid-file pathname; ]
[ statistics-file pathname; ]
[ auth-nxdomain yes(no; ]
[ deallocate-on-exit yes|no; ]
[ dialup yes|no; ]
[ fake-iquery yes|no; ]
[ fetch-glue yes|no; ]
[ has-old-clients yes|no; ]
[ host-statistics yes|no; ]
[ multiple-cnames yes|no; ]
[ notify yes|no; ]
[ recursion yes|no; ]
[ rfc2308-typel yes|no; ]
[ use-id-pool yes|no; ]
[ treat-cr-as-space yes|no; ]
[ also-notify { address-list: };
[ forward only|first; ]
[ forwarders { address-list; }; ]
[ check-names master|slave|response warn|fail|ignore; ]
[ allow-query { address_match_list }; ]
[ allow-transfer { address_match_list }; ]
[ allow-recursion { address_match_list }; ]
[ blackhole { address_match_list }; ]
[ listen-on [ port ip_port ] { address_match_list }; ]
[ query-source [address ip_addr\*] [port ip_portM ; ]
[ lame-ttl number; ]
[ max-transfer-time-in number; ]
[ max-ncache-ttl number; ]
[ min-roots number; ]
[ serial-queries number; ]
[ transfer-format one-answer|many-answers; ]
[ transfers-in number; ]
[ transfers-out number, ]
[ transfers-per-ns number; ]
[ transfer-source ip_addr\ ]
[ maintain-ixfr-base yes|no; ]
[ max-ixfr-log-size number; ]
[ coresize size; ]
[ datasize size; ]
[ files size; ]
[ stacksize size; ]
[ cleaning-interval number; ]
[ heartbeat-interval number; ]
[ interface-interval number-, ]
[ statistics-interval number; ]
[ topology { address_match_list }; ]
[ sortlist { address_match_list }; ]
[ rrset-order { order_spec ; [ order_spec ; ... ] ] };
};

Существует около десятка различных типов значений для этих параметров. Параметры check-names и transfer-format определяются ключевыми словами.
