Checking the start IP and end IP is not sufficient.

I've been down the path you're going.  The best solution I found is:

* Use /rest/report/reassignment/ROOT to get a list of all the 
reassignments for a particular network (it'll be in xls format, you need 
to convert it to something you can parse).
* Go through the list, issue DELETE's for any subnets that are not in 
your database
* Wait awhile (5-10 minutes)
* Go through and issue reassignments for any subnets that are new or 
that ARIN doesn't know about.

It's a large pain to get all the logic working correctly here, but if 
you don't do it you'll be running into overlaps and other errors forever.

I get the distinct feeling that not many people are actually working 
with the API at this point, so it's a pretty painful process.
