A is a public, /26 network for which reverse DNS is not delegated by the ISP. The computers in B, using their private DNS (bind) server D, need to do reverse lookups for IPs in A. Is there a way for D to be authoritative for A's reverse zone, while still querying the DNS in usual manner for IPs outside of A's subnet? (i.e. I don't want D to be authoritative for the entire C-block of IPs). I've read RFC 2317, but I can't find anything useful there because of the non-delegation issue.
