Note: DNAME is equivalent to RFC 2317. In both cases this will break the customers expectation that they can just use x.y.z.in-addr.arpa for the PTR records. Note for reliable local reverse lookups when the external link is down they will need to slave the ISP's x.y.z.in-addr.arpa zone and well as manage the zone the CNAME / DNAME maps to.
