What is "powerdns"

PowerDNS is a DNS server, written in C++ and licensed under the GPL. It runs on most Unix derivatives. PowerDNS features a large number of different backends ranging from simple BIND style zonefiles to relational databases and load balancing/ failover algorithms. A DNS recursor is provided as a separate program.

PowerDNS is a product of the Dutch company PowerDNS.COM BV, with numerous contributions from the open source community. The principal author is Bert Hubert. In March 2015, PowerDNS.COM BV merged with Open-Xchange.
