powerdns

Advanced DNS server with multiple backends including SQL

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. PowerDNS has the concepts of 'backends'. A backend is a datastore that the server will consult that contains DNS records (and some metadata). The backends range from database backends (MySQL, PostgreSQL) and BIND zone files to co-processes and JSON API's. Multiple backends can be enabled in the configuration by using the launch option. Each backend can be configured separately.
