I think there is a couple of things going on here.
1: is the IP space delegated or not? if it is, then there needs to be a local
2: if the ISP is involved then maybe they own the IP space and its not really
delegated. or maybe its shared space don't know.
3: using views are great for splitting IP or fwd zones between internal hosts
and ext hosts. but you still need to own the zones.
i would say have a conversation with the ISP about the reverse zone, and ask
specifically how its setup and why. and if you own the IP space or not and
what the delegation is like.
