ZoneMaster is a tool for zone file and name server management. It consists of a library that can configure BIND and a Web-based user interface that is used to access the data that is stored in a database. A bootstrap script allows you to initialize the database with all necessary information retrieved from an existing configuration. All modifications are saved as jobs in the database, and a job handler makes the necessary changes from time to time. The user interface is based on XSLT-stylesheets and can be easily modified.
