Download PowerDNS Authoritative Server 2.9.22.6

PowerDNS is a dns server with a database as back-end, which makes it easy to manage a large number of dns entries. The developers decided in April 2006 to release the two parts that make up PowerDNS, a recursor and an authoritative name server. This allows new versions to be released faster, according to the developers. The developers have released version 2.9.22.6 of PowerDNS Authoritative Server for the environments that are not yet upgradable to the 3.x branch. The corresponding list of customizations looks like this:
