Finally, IP management systems are usually built around a central SQL database. DNS is, of course, a distributed database technology. When zone data was largely manually edited, the mismatch was less evident. But the steady increase in the use of dynamic update on modern networks has highlighted the inadequacy of these systems. Most use some grievous hack to import dynamically updated data from name servers in the field into the central database, and even then can only do so periodically.
At Infoblox, we're implementing IP address management on an appliance platform. The web-based management software is delivered directly from the appliance, so there's no need to install
software. Moreover, the software includes all of the functions necessary to provision and
maintain the appliances themselves, from a single point, dramatically reducing operating expenses. The appliances are secure, offering only DNS and DHCP - and to authorized addresses, the management interface. Last, and perhaps most significantly, a common, distributed database underlies the appliances, storing both service-specific data (DNS zone data and name server configuration, for example) and appliance configuration.
