Enterprise Class DNS

[bobbarber99 at yahoo.com]

I am working with a company that has implemented Lucent's QIP product.
This is apparently a
repackaging of DNS, DHCP, and so forth with a database backend to drive
it all and some kind
of frontend tools to manage it.

I cannot seem to find much info on QIP.  The Lucent website mentions it
last in the late 1990s.
So ... I have a few questions:

1) Is this a current product?

2) Is there an open source equivalent replacement suite of tools
bundled together this way?

3) When bind is deployed in really large corporate settings, what tools
do you all recommend
    for managing its configuration databases?

Thanks!
