managing DNS

[Greg Rundlett (freephile)]

At work I have over 700 domains to manage.  We use dnsmadeeasy which I
don't find particularly easy.  We also use GoDaddy to register domains
- and GoDaddy includes DNS management tools so I'm inclined to just
use them for both registration and DNS management.

Of course, over time, the DNS records have become very convoluted and
'dirty' with cnames and mx records that don't exist on target hosts
etc.  What I'd like to do is clean it all up and also move it to an
environment where it truly is easy to manage.

Not being a DNS expert, I am supposing that I should be able to export
a zone file for every one of the domains, and then clean them up
manually before importing them into a new (GoDaddy) DNS management
system.  Or maybe it's easier to just transfer and clean up using
(GoDaddy's) DNS management application.

How do I go about transferring and cleaning up my records?  It seems
that I can use a Zone Transfer (AXFR ACL) to copy configuration to
another name server.

Anyone have recommendations on DNS management tools and service
providers?   Why are they good?  One small nicety with DNS Made Easy
is that you can configure internal addresses, so for example
'xerox1.example.com' can point to an internal address like
192.168.1.10 if that is the IP of your Xerox printer.

Experience managing large sets of domains with GoDaddy - and know the
limitations or problems associated with their tools?

Thanks,
