Download PowerDNS Authoritative Server 4.0.1

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 previously decided to release the two parts that make up PowerDNS, a recursor and an authoritative name server, so that a new version can be released more quickly and in a more targeted way, the developers say. The authoritative name server will only respond to a dns lookup if it pertains to the domains for which this server is responsible. The developers have released PowerDNS Authoritative Server 4.0.1. The changes in this release are as follows:
