Nicely put Karl,

There are several FOSS IPAM like systems*. IPAM is an Infloblox 
proprietary system that Cricket Liu is involved with.

CPanel (and look-a-likes), webmin, among many other web GUI based apps 
have some basic DNS configuration capabilities.

Just like the single-sign-on concept, IPAM like tools with a single DNS 
database that manages/configures many BIND DNS servers has proven to a 
useful model.


*Even I put together one 10 years ago that is still being used and 
updated. http://openisp.net/openisp/unxsVZ/wiki
