This may only be a question of me misunderstanding DNS views. I have DDNS setup on my network and it works, my zone is updated when DHCP clients register. I also have split DNS views setup and they work, hosts in different views get different query results returned. The problem is that I have two views: "Unfiltered" and "Default" (names are arbitrary). When a new DHCP host registers, only the "Default" view can see it. So for example, even though both views share the same zone file, only "Default" hosts can do an nslookup against the new host, "Unfiltered" hosts cannot see it using a forward or reverse lookup unless bind is restarted.
