Software to help you manage one or more zones. Licenses are GPL unless noted otherwise. List courtesy of David Nolan - many thanks (contact David info-dns at managedandmonitored dot net). Any errors are entirely ours.
The Carnegie Mellon NetReg package is a scalable and flexible Web-based multi-user system for managing networks, using perl and MySQL. 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. NetReg is designed for enterprise class network management, if you deal with dozens of hosts NetReg is more then you need. However if you deal with thousands or tens of thousands of hosts, NetReg may be exactly what you need. A live demo site is available off of the link above.
A system for generating internal DNS zones, external DNS zones, and DHCP configuration data from the same repository. HostDB is not database driven, doesn't provide a web interface, and isn't designed for managing large networks of hosts, but its great for small networks. You maintain a few small files describing your network and HostDB generates the necessary DNS & DHCP configuration.
DNS Control is a Web-based DNS management tool for BIND 9. It supports maintaining A, MX, and CNAME records, with all information stored in a MySQL database using ADODB. Written in PHP.
Maintain is a multi-user, highly extensible, Web-based management tool for medium to large size computer networks to maintain host information for building configuration files for DNS and DHCP. Written in PHP.
DNSDusty is an uncomplicated Web-based DNS management tool. It does all of its modifications via signed dynamic updates, and gets info on zones via zone transfers. Thus, it does not require any external databases, and plays along well with other tools that do dynamic updates (such as DHCP). DNSDusty is written as a Perl CGI script, so it should work with most Web servers.
