Before rolling your own DNS management platform, take a look at the existing solutions. In addition to the commercial offerings, there is Carnegie Mellon's NetReg, which is apparently both credible and open source.

Disclaimers:  I've never used NetReg, and I work for a company that produces a commercial solution for DNS, DHCP, and IP address management (DDI).
