QIP is just BIND+ with some nice features added. It works
OK with AD if properly configured. They pay attention
to Windows domains (unlike the benign hostility of BIND).
If you can live without AD-integrated zones and secure updates
(either of which may even be in the newest cut - I haven't looked), then
it is hard to justify anything much on technical grounds.
However, regardless of platform, it is ALWAYS better to have local
admin control over the DNS server handling your AD domain.
The big reason is that sooner or later, things break in AD and AD
replication. And when they do, being able to drill down in DNS is
really a requirement to isolating what is going on.
So either your handle your own domain. Or you become an admin and
expert in QIP and/or your DNS admins become expert in solving AD problems.
Or sooner AD will break at the worst possible moment and you'll be
participating in an ugly, protracted, 'finger-pointing' exercise. We've all
been there.
From a technical standpoint, the main issue in down-delegating from
a parent server is to avoid forwarding loops. This is usually a solvable
design problem, but it requires co-ordination between your group
and your QIP group and likely some extra 'hair' on the QIP side.
It is a cleaner design and will be simpler for everyone if you just handle
your local zone and ship everything else upstream to the Vital box. In
this latter scenario I cannot see that a reverse delegation (classful or
classless) would be any kind of real problem, thought the DHCP
topology might be.This hierarchical configuration/ delegation is the
way DNS is designed to be used.
But if it is a matter of 'feifdoms,' when you find a solution to that problem,
please let me know
