Here is the hitch. It is for a application to be used in-house.
Actually several applications with all tied together quite closely.
1. Domain information: owner, webmaster, registrar, email manager, etc.
2. IP address allocation: There are several non-contiguous blocks of
addresses and they tend to be assigned to a specific system or client.
3. DNS things: This will not be a name server but be used build
named.conf and the zone files.
4. And tying the above together an application to let a
tech/support/sales person add a new domain and have it automagically
assigned the correct IPs for web, mail, ftp, and all that other stuff.
5. Finally a application to allow the system people to add, change,
reassign, and delete domain and zone file entries.
