named.conf - configuration file for **named**
SYNOPSIS
named.conf
DESCRIPTION
named.conf is the configuration file for named. For complete documentation about the configuration statements, please refer to the Configuration Reference section in the BIND 9 Administra- tor Reference Manual. 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 <string> { <address_match_element>; ... }; // may occur multiple times controls { inet ( <ipv4_address> | <ipv6_address> | * ) [ port ( <integer> | * ) ] allow { <address_match_element>;
