Dns server configuration files

Zone options include the following: 1. Type master designates the nameserver as authoritative for this zone.

A zone is set as master if the zone file resides on this system. The include statement allows files to be included. This can be done for readability, ease of maintenance, or so that potentially sensitive data can be placed in a separate file with restricted permissions. Both the dnsmasq and systemd-resolved services forward queries for the search domain set in a NetworkManager connection to the DNS server specified in that connection, and forwardes queries to other domains to the connection with the default route.

When multiple connections have the same search domain set, dnsmasq and systemd-resolved forward queries for this domain to the DNS server set in the connection with the lowest priority value.

You can set both the global default and connection-specific ipv4. NetworkManager uses the following DNS priority default values for connections:. This section describes how to override these system-wide defaults with a custom default value for IPv4 and IPv6 connections. Add the [connection] section, if it does not exist:. Add the custom default values to the [connection] section. For example, to set the new default for both IPv4 and IPv6 to , add:. You can set the parameters to a value between and Note that setting the parameters to 0 enables the built-in defaults 50 for VPN connections and for other connections.

The configuration file specifies the type of server it is running on and the zones that it serves as a 'Master', 'Slave', or 'Stub'. It also defines security, logging, and a finer granularity of options applied to zones. This file contains all the data about the machines in the local zone that the server serves.

This file specifies a zone in the in-addr. BIND 8. It also specifies the zones over which the server has authority and which data files it should read to get its initial data. Selectively applied options for a set of zones, rather than to all zones.
