Software Update: PowerDNS Authoritative Server 4.4.0

Spread the love

PowerDNS is a dns server with a database as backend, 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 they can release a new version more quickly and in a more targeted way, the developers said. The authoritative name server will only respond to a dns lookup if it pertains to the domains for which it is responsible. The developers have released PowerDNS Authoritative Server 4.4.0 with the following announcement:

PowerDNS Authoritative Server 4.4.0

We are proud to announce version 4.4.0 of the Authoritative Server.

This release drops GSS/TSIG support, please see PowerDNS Security Advisory 2020-06.

As of now, versions 4.1.x and older are End Of Life.

Version 4.4.0 brings a bunch of exciting changes:

  • the LMDB backend now supports long record content, making it production ready for everybody
  • the SVCB and HTTPS record types are supported, with limited additional processing
  • transaction handling in the 2136 handler and the HTTP API was again improved a lot, avoiding various spurious issues users may have noticed if they do a lot of changes
  • a new setting (consistent-backends) offers a roughly 30% speedup, subject to conditions
  • we finally emit Prometheus metrics!

Authoritative 4.3.x was the last release branch with support for CentOS/RHEL 6. Problems running Authoritative 4.4.x on CentOS/RHEL 6 will not be treated as bugs by us.

We want to specifically thank Robin Geuze, Kees Monshouwer, Mischan Toosarani-Hausberger, Chris Hofstaedtler, and Kevin Fleming for their contributions to this release. We are also grateful to all other reporters of bugs, issues, feature requests, and submitters of smaller fixes and features.

Please make sure to read the Upgrade Notes before upgrading.

The tarball (signature) is available at and packages for CentOS 7 and 8, Debian Stretch and Buster, Ubuntu Xenial, Bionic and Focal are available from
