## Name

`named.conf` — configuration file for named

## Synopsis

`named.conf`

## DESCRIPTION

`named.conf` is the configuration file for named. Statements are enclosed in braces and terminated with a semi-colon. Clauses in the statements are also semi-colon terminated. The usual comment styles are supported:

C style: /* */

C++ style: // to end of line

Unix style: # to end of line

## ACL

acl `string` { `address_match_element`; ... };

## CONTROLS

keys { `string`; ... } ];
unix `quoted_string` perm `integer`
owner `integer` group `integer` [
keys { `string`; ... } ];
};

## DLZ

dlz `string` {
