dnsdist 1.1.0 released

We are very pleased to announce the availability of dnsdist 1.1.0. There have been very few changes since 1.1.0-beta2, the most significant ones being that we now handle header-only responses, and that “Refused” responses are now handled by the cache in the same way as “ServFail” ones.

dnsdist 1.1.0 has seen a significant amount of development, mostly based on feedback from they many 1.0 deployments. The majority of the new features have already been taken into production by pre-release and beta users.

Highlights include:

  • TeeAction: send queries to a second nameserver, but ignore responses. Used to test new installations on existing traffic. Also used by the Yeti rootserver project.
  • Response rules which act on received responses
  • AXFR/IXFR support, including filtering options
  • Linux kernel based query type and query name filtering (eBPF), for very high speed packet rejection. Includes counters and statistics
  • Query counting infrastructure (contributed by TransIP’s Reinier Schoof)

For the many other new features, improvements and bug fixes, please see the dnsdist website for the more complete changelog and the current documentation.

Release tarballs are available on the downloads website.

Several packages are also available on our repository.
