Wow, LOL!

The software product is called a "text editor".

Look at your list of assignments in your NS .arpa. file:
 1) Find a subnet that hasn't been assigned.
 2) Update the text file.
 3) Wait for it to propagate.
 4) Tell the customer.

The concomitant procedure for static host assignment is:
 1) Find a number that hasn't been assigned.
 2) Update the text file.
 3) Wait for it to propagate.
 4) Then, and only then, update the forward NS file(s).
 5) Tell the customer.

Of course, there is software that will automatically maintain the files,
and even send a signal to bind, but I've alway found them to be weak at
subnet management.  Text editor is the way to go -- using subversion for
"distributed" file management (that is, knowing who to blame for mangling
the assignment commit).
