	Your upsteam doesn't know how to correctly get this space
	delegated to you.  Telling you that you have to have each
	individual address as a seperate zone is ridiculous.  They
	should be co-ordinating the delegation with ARIN.  ARIN is
	setup to handle sub delegations like this.  They deal with
	them all the time.

	Get your ISP to talk to ARIN.
