First Release Candidate for Authoritative Server 4.6.0

Jan 14, 2022


Today we released the first Release Candidate for Authoritative Server version 4.6.0.

Version 4.6.0 mostly brings small improvements and fixes, but there are three notable new features:

  • support for incoming PROXY headers
  • support for EDNS cookies
  • autoprimary management via pdnsutil and the API

Support for PROXY headers allows you to put a load balancer (such as dnsdist) in front of the Authoritative Server, while still having the Auth see the actual IPs of clients talking to it.

EDNS Cookies allow resolvers that support it to have an extra layer of authentication on their communication with the Authoritative Server.

Compared to 4.6.0-alpha1, the major user visible change is the new NSEC3PARAM settings – check the upgrade docs below for more information. Besides that, various bugs have been fixed.

A full list of changes can be found in the changelog.

Please make sure to read the Upgrade Notes before upgrading.

The tarball (signature) is available at Packages for various distributions are available from

Please send us all feedback and issues you might have via the mailing list, or in case of a bug, via GitHub.
