The Carnegie Mellon NetReg package is a scalable and flexible Web-based system for managing networks. It consolidates information about DNS zones, subnets, machine registrations, and DHCP configuration, and provides tools for easy management. The system exports ISC BIND configuration and zones, and can update them via either static zone files or TSIG signed dynamic DNS updates. It also exports ISC DHCP configurations, and has a SOAP API for integration with other systems.
