PowerDNS Authoritative Nameserver

The PowerDNS Authoritative Server is a versatile nameserver which supports a large number of backends. These backends can either be plain zone files or be more dynamic in nature.

Examples of backends include relational databases, other DNS data formats and coprocesses.

Backends

PowerDNS has the concepts of 'backends'. A backend is a datastore that the server will consult that contains DNS records (and some meta-data). The backends range from database backends (Mysql, PostgreSQL, Oracle) and Bind-zonefiles to co-processes and JSON API's. For more in-depth information, see Modules & Backends in the documentation on internals.

Multiple backends can be enabled in the configuration by using the launch option. Each backend can be configured separetly.
