This command allows managing DNS zones used for controlling what servers users are directed to when connecting. Omitting all parameters prints out the status of the DNS zone.

ADDZONE, DELZONE 

adds/removes a zone, eg us.yournetwork.tld. Servers can then be added to this zone with the ADDSERVER command.

Default Configuration

/*
 * os_dns
 *
 * Provides the command operserv/dns.
 *
 * This module requires that m_dns is loaded.
 *
 * This module allows controlling a DNS zone. This is useful for
 * controlling what servers users are placed on for load balancing,
 * and to automatically remove split servers.
 *
 * To use this module you must set a nameserver record for services
 * so that DNS queries go to services.
 *
 * Alternatively, you may use a slave DNS server to hide service's IP,
 * provide query caching, and provide better fault tolerance.
 *
 * To do this using BIND, configure similar to:
 *
 * options { max-refresh-time 60; };
 * zone "irc.example.com" IN {
 *   type slave;
 *   masters { 127.0.0.1 port 5353; };
 * };
 *
 * Where 127.0.0.1:5353 is the IP and port services are listening on.
 * We recommend you externally firewall both UDP and TCP to the port
 * Anope is listening on.
 *
 * Finally set a NS record for irc.example.com. to BIND or services.
