NetDB is a suite of applications for managing DNS and DHCP in a distributed, collaborative fashion. It is geared towards very large networks and can support thousands of nodes, networks, and users. NetDB consists of a database with Web, command-line, and RMI interfaces. Users use the NetDB Web and command-line interfaces to keep the data in NetDB up to date. The GSSAPI-secured RMI interface can be used to create site-specific tools to manage and use NetDB data. NetDB includes scripts for generating ISC BIND zonefiles and ISC DHCP configuration files.
