BIND 9.11.0 Introduces Catalog Zones


Catalog Zones provide a new method for provisioning zones on secondary servers. Previously, the user had to provide a script, or some other method, for adding new zones to the secondary servers.  The DNS standard IXFR/AXFR would update those zones as the content changed, but it would not add and delete the zones.

Now, with Catalog Zones, you may be able to retire your custom scripts for updating zone lists on secondary servers.

A catalog zone is a regular DNS zone which contains a list of “member zones”, along with the configuration options for each of those zones. When a server is configured to use a catalog zone, all the zones listed in the catalog zone are added to the local server as slave zones. When the catalog zone on the Master is updated (e.g., by adding or removing zones, or changing configuration options for existing zones) those changes will be put into effect on all secondary servers using that catalog.

We plan to release the BIND 9.11.0 on August 30th. Please note that with this release we are changing the open source license agreement for BIND from the ISC license to the Mozilla Public License 2.0 (MPL 2.0).
